The aim of quantum metrology is to exploit quantum effects to improve the precision of parameter estimation beyond its classical limit. In this paper, we investigate the quantum parameter estimation problem with multiple channels. It is related but not limited to the following two important and practical quantum metrology problems:(i) Quantum enhanced metrology with control, whose aim is to improve the precision of quantum sensing by utilizing feedback or open-loop control;(ii) Practical quantum metrology where the underlying evolution of quantum probes may change from a unitary dynamics to an open system dynamics,owing to the inevitable decoherence during the quantum sensing operation. For various kinds of quantum multiple channels, the corresponding quantum channel Fisher information is derived. To demonstrate the results, some illustrative examples are given.

This paper proposes a novel data-driven finite-time adaptive control method for the spacecraft attitude tracking control problem with inertial uncertainty. Based on the dynamic regression extension technique, the disturbance unit matrix is introduced, and the parameter estimation law in the form of algebraic equations is presented, which realizes the arbitrarily small convergence of parameter estimation error. The convergence of parameter estimation errors is verified through stability analysis. Globally non-singular fast terminal sliding mode control is designed to achieve finite-time arrival of the sliding surface and convergence of the system state error. The stability analysis of the closed-loop system demonstrates the effectiveness of the proposed method. Furthermore, the effectiveness and superiority of the proposed method are verified through numerical simulations of spacecraft attitude tracking control. © 2025 COSPAR

This paper presents the design of supervisory model predictive control for HVAC systems and two zones. The supervisory control (SC) is designed to find the optimal reference temperature of each zone. The design criteria consist of the total operating cost (TOC) and the thermal comfort cost (TCC). Then, the model predictive control (MPC) is designed to track the optimal reference signals. When SC and MPC are designed for two zones simultaneously, they are referred to centralized SC and centralized MPC. On the other hand, when SC and MPC are designed for two zones separately, they referred to decentralized SC and decentralized MPC. We then compare the results between the decentralized control and the centralized control. The trade-off curve shows that the performance of centralized control is better than that of decentralized control. In particular, centralized MPC improves the performance in tracking reference signals. Furthermore, TOC of centralized control is lower than that of decentralized control. It can be concluded that the centralized control is appropriate for two zones in terms of the tracking of reference and the electrical charge. © 2023 ICROS.

The combination of Electric Autonomous Vehicles (EAVs) and renewable energy aligns with sustainability goals. However, to achieve these goals, it’s necessary to implement a robust control system for the key component that drives the vehicle, specifically, the electric motor. This paper explores the control of Induction Motor pursuing the Required Performance Standards for Autonomous Vehicles. The primary objective is to build a robust control system to achieve this, the first approach is the Indirect Rotor Field Oriented control (IFOC), the Latter is implemented along with a PI controller, Lastly Model Reference Adaptive control by Hyperstability Criterion is introduced. A detailed analysis is carried out using MATLAB Simulink, which shows the efficiency of adaptive control not only in speed tracking, but also in parameter variation and disturbance. The comparative analysis between PI and Hyperstability control method validates the theory asserting the robustness and insensitivity of adaptive control to parameter uncertainty and disturbances. Furthermore, it convincingly demonstrates that the latter outperforms traditional classic controllers. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2024.

This paper deals with an analysis regarding the effect of Sewer Network operation on the performances of the integrated wastewater collecting and treatment system. The analysis is done by considering various control actions for the output storage tank of the sewer network, comparing a series of performance indicators defined for both subsystems with their "no control" value. Two cases have been considered regarding the control actions for the output storage tank of the sewer network: 1. keeping the output valve at a constant opening and 2. keeping the output valve at the maximum opening possible such as the outflow is limited to a constant value. While the second case did not prove advantageous, the first one showed that lowering the sewer network output valve opening would improve the integrated system performances. © 2023 IEEE.

The paper examines the influence of the working fluid temperature on power losses in an electro-hydraulic servo system. The behavior of the system has been investigated under Proportional-Integral (PI) control at different working fluid temperatures and various control setpoints. An Adaptive PID controller has been synthesized, utilizing feedback from sensors to measure various system parameters (such as temperature, pressure, and RPM), and then adapting the parameters of the P, I, and D components of the controller based on this data to achieve optimal regulation. © 2023 IEEE.

Online Path Planning of Messenger UAV in Air-Ground Coordination Over Urban Areas

引用

IEEE Transactions on Vehicular Technology 2024年第5期74卷 7135-7151页

Fast-moving unmanned aerial vehicle (UAV), serving as a messenger to visit ground vehicles (GVs) for information relays, can be applied to complex tasks in urban environments, such as air-ground cooperative urban rescue and UAV-assisted data collection. Existing work ensures that the UAV visits all GVs by assuming that it knows the motion parameters of GVs (e.g., velocities or paths) at any given time. However, in practice, GVs may not move with anticipated velocities due to motion uncertainties. This UAV path planning problem can be formulated as a Dynamic Dubins Traveling Salesman Problem with Uncertain Neighborhoods (DDTSPUN). The problem involves variables with complex interdependencies (e.g., the visiting sequence of the UAV to GVs and the access location of the UAV to GVs) and requires solving a sequence of uncertain encounter problems. To address the uncertainty in GV motion, we define robust neighborhoods and corridors and prove that the UAV can revisit GVs reliably by visiting these areas. By flying the UAV through robust areas, the DDTSPUN can be transformed into a deterministic optimization problem, namely Revisit-time-constrained Dubins Traveling Salesman Problem with Neighborhood (RDTSPN), which provides a simplified model and compresses the solution space. To address the RDTSPN, we propose an online heuristic path planning algorithm. It incorporates a gradient-based method for visiting robust neighborhoods and a sampling-based search strategy along robust corridors to obtain the Dubins paths of the UAV that achieve robust visit for each GV. Finally, the computational experiments, including representative instances, random instances with different scales, and an instance generated using real-world data, demonstrate its advantages over other state-of-the-art algorithms in obtaining the shortest path that satisfies UAV curvature constraints while ensuring robust access to all GVs. © 1967-2012 IEEE.

This paper deals with the increasing of the operation efficiency of a wastewater treatment plant by reducing the level of pollutant concentration in the effluent. In essence, the main goal is the reduction of the concentration of organic substrate, Model Predictive control algorithm being used for this, considering as a model of the wastewater treatment process a neural network model based on a simplified mathematical model of the 4th order. For the implementation of the control algorithm, two neural networks were trained. In the first version of the neural network, it was considered that all 4 state variables are measurable and in the second version, only the organic substrate was considered measurable. Regarding the training of the two neural networks, good results were obtained in the case of both versions. Instead, the control algorithm gave better results when the second neural network was used (lower values of the substrate, lower variations of the aeration rate, which means a lower cost of operation). © 2023 IEEE.

Electric Vertical Takeoff and Landing (eVTOL) aircraft has gained significant attention as a basic element of urban air mobility (UAM), a potential solution for urban transportation challenges using low-altitude urban airspace. Ensuring the safe operation of eVTOL is crucial for UAM applications, which are related to various professional fields such as aerodynamics, control, structures, and power systems. This article systematically analyzes the characteristics of different design configurations, including multi-rotor, lift+cruise, and tilt-rotor types of eVTOL. The advantages and limitations of each type of eVTOL are analyzed. After that, the overall design problems are analyzed, and challenges of eVTOL control system design are discussed from aspects of overall control structure and subsystems, such as controller, sensors, actuators, and command generator. This article tries to fill the gap in the eVTOL design from a control perspective and provides some resolutions for the eVTOL application. IEEE
