摘　　要：针对强非线性复杂时变的电子节气门,研究了一种基于回声状态网络的复合智能控制器,并给出了该复合智能控制器的结构和实现方法。该复合智能控制器由前馈控制器和反馈控制器两个部分组成。前馈控制器为一个基于回声状态网络的逆模型控制器,用于抵消电子节气门的非线性特征;反馈控制器是PID控制器,用于补偿逆模型的建模误差,提高系统的鲁棒性。仿真实验表明,该控制器的实际效果良好。An echo state networks based composite intelligent controller for complex nonlinear time-varying electronic throttle is proposed,and the structure and implementation of the proposed controller is provided. The proposed controller includes a feedforward controller and a feedback controller. The feedforward eontroller is an inverse model controller, which can eliminate the nonlinearity of the plant, and is implemented by using echo state networks modeling. The feedback controller is a PID controller which serves as the compensator and improves the robustness. The simulation results show that it has good performance.
