基于SDRE方法的汽车线控转向系统控制方法研究
Research on SBW System＇s Control Method Based on SDRE Technique
摘要
Abstract
This paper studied the controller of a SBW system via a SDRE technique. Based on the vehicle dynamics and the tire model,the state dependent coefficient（SDC） form of the SBW was estab- lished. Since the dynamic equations were highly non--linear, the controller was designed with a SDRE technique. Finally,the controller was solved using θ--D method because it had outstanding computing efficiency and sufficient control accuracy. The simulation results show that the SDRE method has bet- ter tracking precision and improves steering stability and reduces motor energy consumption.关键词
