摘要
传统的PID控制方法只对控制回路内的干扰因素具有较好的鲁棒性。而对控制回路外的干扰因素如传感器误差等很难消除。为此,本文提出了基于卡尔曼+PID滤波器的离散电子节气门控制方法。先利用卡尔曼滤波器对节气门传感器的测量误差及非线性干扰因素等进行滤波,再将滤波后的状态量用离散的PID控制。通过仿真实验表明,用该方法与传统PID相比能提高控制节气门的抗干扰和跟随性能指标。
The traditional PID control method has good robustness to the disturbance factors in the control loop,but it is difficult to eliminate the interference factors outside the control loop such as sensor error. For this purpose,this paper proposes a discrete electronic throttle control method based on Kalman＋PID filter,which firstly uses Kalman filter to filter the measurement error and nonlinear interference factor of throttle sensor,then uses the discrete PID to control filtered state quantity. The simulation results show that this method can improve the anti-jamming and performance index of electronic throttle compared to the traditional PID.
