Research on Automotive Wire-controlled Steering Controller Based on Rapid Control Prototype
In order to improve the control performance of linear steering control system with rapidity,accuracy and stability,this paper builds a RCP test platform based on the rapid control prototype technology,and compares the effects of different control strategies on the control performance of the linear steering system.With the establishment of the mathematical model of the executive motor,the PD controller,cascade three closed loop PID controller and fuzzy PID controller are gradually designed and optimized according to their dynamic characteristics,and the step response performance of the three controllers is analyzed.The RCP rapid prototype control test platform is built based on dSPACE design,the following performance of the controller is tested in semi-physical simulation and the performance advantages and disadvantages of the controller are compared and analyzed.The results show that the fuzzy PID control strategy is superior in the control of corner following performance.
