摘要
提出了一种电动助力转向系统回正控制算法以提高转向盘的回正性。开发了一种基于转向盘转角估计的PID控制算法 ,该控制算法不需要转向盘转角或者电动机转速传感器 ,降低了控制系统的成本。同时 ,对提出的控制算法进行了仿真 ,并与其它回正控制算法的试验进行对比 。
To improve steering wheel returnability,a PID control algorithm based on the estimation of steering wheel angle is developed for electric power steering system.Neither steering wheel angle nor motor speed sensor is required for the algorithm,so the cost of the system can be reduced.Simulations and comparison are conducted for different returnability control algorithms.The results show that the proposed algorithm can improve the returnability and stability of steering wheel.
