摘要
针对强非线性复杂时变的电子节气门,研究了一种前馈-反馈复合控制器。该复合控制器包括前馈控制器和反馈控制器两个部分,前馈控制器为一个逆模型控制器,用于抵消电子节气门的非线性特征,该逆模型由支持向量机算法辨识得到。而反馈控制器是一个PID控制器,用于补偿逆模型的建模误差并提高系统的鲁棒性。仿真实验表明该复合控制器的实际效果良好。
A novel feedforward-feedback composite controller （ FFCC ） for complex nonlinear timevarying electronic throttle is proposed. The proposed FFCC includes a feedforward controller and a feedback controller. The feedforward controller is a inverse model controller,which can eliminate the nonlinearity of the plant and it is implemented using support vector machines（ SVM ）modeling. The feedback controller is a PID controller which serves as the compsentor and improves the robustness. Simulation results show that the proposed FFCC has good performance.
