Fault Tolerant Control of Electric Power Steering System Sensor and Its Simulation Analysis
摘要
Abstract
By means of analyzing the dynamic model of EPS system, the paper obtained the relationship among output torque of the steering column, effective output torque of the motor and ground reaction torque. When the torque sensor fails, it calculated the approximate output torque of the steering column by way of both in the latter, and processed the estimate value with the Butterworth filter in order to eliminate the white noise of the system. Finally by use of Matlab/Simulink software, it made the simulation of fault-tolerant control system. The simulation results show that the estimate can reflect the sensor measurement accurately. In the case of sensor failure, EPS fault-tolerant control system can use the estimated value of the sensor to maintain the stability of control system so as to improve the car 's handling-stability and driving-safety.关键词
