The coordinated parallel driving of autonomous vehicles in formation not only optimizes road space utilization but also enhances road efficiency, contributing to the reduction of traffic congestion. Hence, it is necessary to impose diverse constraints on the vehicle to ensure its adherence to the intended trajectory. The constraints of mechanical systems are generally categorized into equality constraints and inequality constraints. This paper adopts a constraint-following methodology by leveraging the generalized Udwadia-Kalaba equation to design the self-driving vehicle formation system, considering both equality and inequality constraints within the system. Simulation experiments demonstrate that the method is not only simple and effective but also has good applicability in swarm systems.

This article presents a refined fixed time sliding-mode observer (FTSMO) developed for wide-speed sensorless control of permanent magnet synchronous generator wind turbines (PMSG-WTs). The proposed approach enables the estimation of speed and position in the alpha beta frame with the help of Arc-tan block, which is a requirement in back-electromotive force (EMF) estimation-based methods. This not only lightens the computational load on the controlsystem but also simplifies the challenge of determining PLL design parameters. Moreover, an innovative terminal sliding surface is utilized to improve the reaching phase, resulting in a faster convergence rate with higher accuracy in estimations compared to conventional terminal sliding techniques. The finite-time convergence of the proposed estimation scheme is verified using the Lyapunov theorem, ensuring that estimation errors converge to zero within a specified time frame, regardless of initial conditions. MATLAB/Simulink simulations are carried out to assess the performance of the sensorless method on a 18-kW PMSG-WT. The results demonstrate a quicker convergence time relative to Extended Kalman Filter (EKF) observers.
In addition to meeting basic electrical characteristics, the design of a microwave circuit must also consider the ease and accuracy of the circuit model, the time required for circuit design, the availability of toler...
