This paper presents a new approach to the existence of optimal continuous control strategies for broad classes of nonlinear systems with bounded nonlinearities. Innovation of the proposed method lies in the design of the Extended High-Differentiating Gain Linearizing Corrective Observer (EHDGO). This observer is adapted to provide a broader linearization horizon and serves as the linear estimator in the proposed approach. designing such observer requires a new approach to linearization that takes into account the extended time horizon, relation to initial conditions, and extended differential properties. Proposed linearization involves approximating the nonlinear system model by projecting it onto predefined orders and the differentiating properties of the linear model. To enhance differentiation properties of the estimator, a preliminary gain based on the Nyquist criterion was used. Stabilization of a nonlinear system in a closed-loop is achieved using the Linear Quadratic Regulator (LQR) theorem for proposed estimator.

Traditional power big data processing methods can no longer meet the development trend of power big data. designing and implementing high-performance power big data servers for real-time collection, analysis, and processing of power big data has become the development direction of domestic power big data. This article proposes a design pattern based on reactor servers. By constructing the system software and combining "data-driven"and "theoretical model"methods, the data parsing layer of the power data transmission message format based on the 104 protocol is implemented, achieving the function of changing the log printing level without the need for system restart. Through experimental testing and analysis at the end of the article, The comparison of data throughput between this system and OpenPDC has successfully verified the system's advantages in concurrency performance. The test results indicate that the throughput of this system is on average more than 20% higher than OpenPDC. © 2023 ieee.

The purpose of this paper is to discuss the challenges of coping with the difficulties in the development of UAV flight control algorithms, and to propose a design scheme for a semi-physical UAV flight control system in view of the risks in flight, the limitation of experimental conditions, the debugging time and the hardware cost. The innovative aspect of this design lies in its ability to significantly improve the stability and efficiency of flight control algorithm development by integrating semi-physical simulation with real-time monitoring and graphical programming. This approach allows for safer and more cost-effective testing and optimization of UAV flight control ***, the functional modules were divided into different categories, and the communication relationship between the modules was carefully evaluated. Secondly, the hardware and software selection of the system were introduced in detail, and the most suitable hardware model and software system for the system were carefully designed, so as to build a complete system architecture. Subsequently, the functional implementation process of the system was comprehensively elaborated, including interface pre-compilation, graphical programming and host computer data monitoring, so that the development, debugging and monitoring of flight control algorithms could be effectively realized. This design solution greatly improves the efficiency of algorithm development, so that developers only need to focus on the algorithm design of the core control part and embed it in the complete code module to carry out algorithm development and performance testing. © 2024 ieee.

After decades of development, flow-based microfluidic biochips have become one of the most promising platforms for biochemical experiments. control ports, which are remarkably area-consuming punch holes, are interfaces to external pneumatic controllers. To prevent the inserted outer catheters from hindering microscopic observation during experiments, control ports are placed on chip boundaries in practice. In this paper, we propose a practical and novel control layer escape routing methodology, which efficiently connects microvalves to user-specified boundaries. Particularly, the proposed methodology groups certain microvalves, and constructs a tree to connect them with the same control port, which is regarded as the root of the tree. Clustering more microvalves into the same group can reduce the usage of control ports, but will lead to more intensive connections among microvalves, which becomes larger obstacles for the routing of other microvalves outside the group, thereby reducing the routability. To derive an optimized tradeoff between the control port usage and the routability, we adapt a hierarchical clustering algorithm with a dynamically changing threshold that ascertains the closeness of the microvalves. We also adopt the Bayesian optimization (BO) to determine the optimized routing order for better routing results. Additionally, we propose a fault-tolerant structure as an option for users, which only occupies little area around control channels, and significantly improves the reliability against blockage defects. Experimental results demonstrate that the proposed methodology can efficiently connect all microvalves to user-specified boundaries, significantly reduce control port usage, shorten control channels, and improve reliability compared to baseline methods. © 2024 Copyright is held by the owner/author(s).

Thermal and Voltage-Aware Performance Management of 3-D MPSoCs With Flow Cell Arrays and Integrated SC Converters

Flow cell arrays (FCAs) concurrently provide efficient on-chip liquid cooling and electrochemical power generation. This technology is especially promising for 3-D multiprocessor systems-on-chip (3-D MPSoCs) realized in deeply scaled technologies, which present very challenging power and thermal requirements. Indeed, FCAs effectively improve power delivery network (PDN) performance, particularly if switched capacitor (SC) converters are employed to decouple the flow cells and the systems-on-chip voltages, allowing each to operate at their optimal point. Nonetheless, the design of FCA-based solutions entails nonobvious considerations and tradeoffs, stemming from their dual role in governing both the thermal and power delivery characteristics of 3-D MPSoCs. Showcasing them in this article, we explore multiple FCA design configurations and demonstrate that this technology can decrease the temperature of a heterogeneous 3-D MPSoC by 78 degrees C, and its total power consumption by 46%, compared to a high-performance cold-plate-based liquid cooling solution. At the same time, FCAs enable up to 90% voltage drop recovery across dies, using SC converters occupying a small fraction of the chip area. Such outcomes provide an opportunity to boost 3-D MPSoC computing performance by increasing the operating frequency of dies. Leveraging these results, we introduce a novel temperature and voltage-aware model-predictive control (MPC) strategy that optimizes power efficiency during runtime. We achieve application-wide speedups of up to 16% on various machine learning (ML), data mining, and other high-performance benchmarks while keeping the 3-D MPSoC temperature below 83 degrees C and voltage drops below 5%.

To realize a fault-tolerant quantum computer with a large number of qubits, a dedicated control system is essential. Achieving such a control system requires a quantitative evaluation of bottlenecks and scalability, considering actual device implementations. In this presentation, we provide initial quantitative evaluation results of power consumption, performance, and area for the back-end of the control system implemented using ASICs with CMOS technology across multiple technology nodes.

Polynomial-Time Reachability for LTI systems With Two-Level Lattice Neural Network controllers

In this letter, we consider the computational complexity of bounding the reachable set of a Linear Time-Invariant (LTI) system controlled by a Rectified Linear Unit (ReLU) Two-Level Lattice (TLL) Neural Network (NN) controller. In particular, we show that for such a system and controller, it is possible to compute the exact one-step reachable set in polynomial time in the size of the TLL NN controller (number of neurons). Additionally, we show that a tight bounding box of the reachable set is computable via two polynomial-time methods: one with polynomial complexity in the size of the TLL and the other with polynomial complexity in the Lipschitz constant of the controller and other problem parameters. Finally, we propose a pragmatic algorithm that adaptively combines the benefits of (semi-)exact reachability and approximate reachability, which we call L-TLLBox. We evaluate L-TLLBox with an empirical comparison to a state-of-the-art NN controller reachability tool. In our experiments, L-TLLBox completed reachability analysis as much as $5000\times$ faster than this tool on the same network/system, while producing reach boxes that were from 0.08 to 1.42 times the area.

Industrial control systems (ICS) are increasingly becoming targets for cybercriminals seeking ransom or aiming to cause disruptive chaos because of the potentially devastating impact of ICS malfunction. Following the security-by-design principle, security measures should be integrated into ICS system design as early as possible. system architecture design is one of the earliest activities in the system development life cycle that can play a key role in enhancing security. Hence, this paper proposes an architectural security framework based on IEC 42010, a standard for system architecture description, aiming at integrating security into system architecture. As part of this framework, an ontology is designed to formalize the system architecture described in SysML v2 (systems Modelling Language version 2) to facilitate automatic reasoning about system design against specified security requirements and rules. To this end, the transformation rules from the textual notation of SysML v2 to OWL (Web Ontology Language) are specified. A use case is presented and analyzed that demonstrates the practicality of the proposed approach in adding security to the system architecture. © 2024 ieee.

In the utilization of multirotor UAVs for the transport of suspended payloads, a good level of accuracy and precision, with minimal vibration of the multirotor, and stability of the payload are desired characteristics. However, owing to the nonlinearity of the control design and the often underactuated nature of the UAV, designing a robust control for the system presents an interesting challenge. Furthermore, the system is subjected to both internal and external uncertainties and disturbances which may not always be mathematically defined. Hence, this research work proposes a multi-surface sliding mode controller, aided by RBF Neural Networks to approximate external disturbances that a multirotor UAV is subjected to. First, the dynamics of the multirotor with a suspended payload, represented by a single pendulum, will be presented. To ensure tracking stability, a multi-surface sliding mode controller based on an adaptive RBF neural network will then be proposed. Simulation results are presented to validate the effectiveness of the proposed controller. © 2024 ieee.
