LPV design of fault-tolerant control for road vehicles

Abstract

The aim of the paper is to present a supervisory decentralized architecture for the design and development of reconfigurable and fault-tolerant control systems in road vehicles. The performance specifications are guaranteed by the local controllers, while the coordination of these components is provided by the supervisor. Since monitoring components and the FDI filters provide the supervisor with information about the various vehicle maneuvers and the different fault operations, it is able to make decisions about the necessary interventions into the vehicle motions and guarantee the reconfigurable and fault-tolerant operation of the vehicle. The design of the proposed reconfigurable and fault-tolerant control is based on an LPV method that uses monitored scheduling variables during the operation of the vehicle.

Research on Path Tracking Fault-Tolerant Control Strategy for Intelligent Commercial Vehicles Based on Brake Actuator Failure

“…Fault-tolerant control currently has two development directions: active fault-tolerant control and passive fault-tolerant control [10,11]. In the field of vehicle fault-tolerant control, scholars have proposed a variety of active and passive fault-tolerant control strategies, including sliding mode control [12,13], adaptive control [14][15][16], fuzzy neural network control [17,18], and robust H∞ and LPV control [19][20][21][22]. Passive fault-tolerant control is advantageous over active fault-tolerant control because it does not require fault detection and isolation units.…”
