基于Riccati方程的汽车线控转向传感器故障重构研究
Research on the Sensor Fault Rebuilding Based on Riccati-type Equation for Steer-by-wire System
摘要
Abstract
Since the safety and reliability problem of SBW system after canceling the mechanical connection between steering wheel and steering gear,a sensor fault rebuilding method for SBW system was proposed based on software analysis redundancy. On the basis of existing SBW system,from the view of optimal control,a optimal software analysis fault rebuilding method for SBW key sensor system was put forward based on Riccati-type equation. The sensor fault rebuilding hardware in the loop simulation was carried out, and the results show that the method can achieve the fault rebuilding of the sensors' signals,and can satisfy the fault tolerant control desire of the SBW system.关键词
