This paper explores the stability problems of discrete-time linear time-invariant (LTI) systems subject to random time delays. We first develop a general mean-square small-gain stability condition for feedback systems containing structured stochastic multiplicative uncertainties. Subsequently, we apply this mean-square small-gain condition to certain LTI random delay systems, where delays exhibit random delay lengths. Necessary and sufficient mean-square stability criteria are derived. These criteria, applicable to systems with either single or multiple sources of random delays, typically involve computing the spectral radius of a constant matrix. This computation allows us to determine whether a system's state variance matrix converges asymptotically despite the presence of random delays.

The safe operation of Autonomous Vehicles (AV) primarily relies on effective collision avoidance techniques. Therefore it is essential to integrate obstacle avoidance features into the motion planning of vehicles. This research focuses on obstacle avoidance using the CBF which has evolved as an efficient mathematical tool for unmanned vehicles to ensure safe navigation. A Quadratic Programming (QP) problem for collision avoidance is formulated using CBF as a constraint. The Hamilton-Jacobi-Bellman (HJB) equation derived for the QP problem gives rise to a Partial Differential Equation (PDE), the solution of which generates the necessary control input for the vehicles to successfully avoid the obstacles. The key novelty of this research lies in solving the HJB equation using a multi-layer perceptron, called a Physics-informed Neural Network (PINN), which needs less computation in a cluttered environment. The proposed methodology integrates the safety and reliability aspects of CBF with an obstacle avoidance solution using PINN (OA-PINN). The performance of OA-PINN is validated using numerical simulations and related hardware experiments.

The increasing availability of cloud computing services has revolutionized industrial productivity by providing essential tools for data storage, data transfer, and computation. In a cloud-based control system (CCS), the controller is located in the cloud, thereby enabling complex computation processes such as nonlinear model predictive control (NMPC). Using cloud computing, expensive control algorithms can be deployed without the upfront cost of a local computing unit. The computation time can be drastically reduced due to the improved computing power, which is important in the case of systems with fast dynamics in combination with NMPC-based control to maintain the existing time step size with regard to the calculation time. Placing the controller in the cloud also introduces communication latency in the control loop. It has been highlighted in former studies that computation time and communication latency can reduce the reliability and stability of a CCS. This paper proposes a cloud-based model predictive control strategy that extends simple time delay compensation with event-based control to reduce the effect of computation and communication delays. The optimal input variable sequence is used until a new sequence is available. This event-based method reduces the amount of communication and redundant calculations. The developed CCS algorithm is implemented in the real-time control of an experimental pendulum crane system. The effects of the proposed algorithm in mitigating computation and communication delay are compared to another CCS strategy that only uses the first element of the sequence.

This research paper explores the application of the Ignition Supervisory control and Data Acquisition (SCADA) system with the Allen-Bradley Programmable Logic controller (PLC) within a mechatronics station context. The mechatronics station, situated in the Industrial control and automation Lab at Michigan Technological University, serves as the testing ground for this integration effort. The primary objective is to link the PLC with Ignition software while also developing a tailored webpage interface. Central to this setup is the incorporation of an ultrasonic sensor within the mechatronics station. This sensor is instrumental in measuring the height of parts housed on the part holder, enabling the system to discern between good and bad parts based on height differentials. Through the synergy between Ignition SCADA software and the Allen-Bradley PLC, several benefits are realized, notably including enhanced real-time monitoring, streamlined data acquisition processes, and the facilitation of remote access capabilities. This study aims to elucidate the technical intricacies of integrating these systems, as well as to highlight the practical advantages they offer in industrial automation settings. By delving into the specifics of implementation and functionality, this research seeks to contribute to the broader discourse surrounding the optimization of mechatronics systems through advanced SCADA-PLC integration methodologies.
