Robust Fault-Tolerant Control of High-Speed Trains Based on the Solution of Riccati Equation

In this paper, a robust fault-tolerant control strategy based on the solution of Riccati equation are developed for the velocity tracking control of the high-speed trains subjected to the actuator faults. For each separate actuator with occurrence of faults, a robust fault-tolerant control is performed by an appropriate solution of Riccati equation. According to the proposed robust fault-tolerant control law, a new feedback controller which can stabilize the faults system is designed. It is simulated and proved to be very useful and effective by the satisfactory numerical simulation results of the robust fault-tolerant high-speed train control system.
