为解决传统线性控制器无法满足汽车电子节气门控制要求的问题，利用自抗扰控制技术进行了电子节气门非线性控制器研究。首先根据博世公司的电子节气门性能指标，给出了参考过渡过程和采样时间的选取准则；然后通过将建模误差等不确定性看作加性外部扰动，利用扩张状态观测器实时估计出作用于系统的扰动总和，并给予补偿。仿真表明，基于自抗扰控制技术的控制方法能够很好地实现电子节气门的快速跟踪控制，而且具有较强的鲁棒性。

The nonlinear controller of electronic throttle(ET)is designed to improve the control performance of electronic throttle, based on active disturbance rejection control technique(ADRCT).Firstly,the criterion of reference profile generation and sam-pling time is given,according to the performance provided by BOSCH.Then,both the model error and external disturbance are considered as addition external disturbance,which are estimated and compensated by the extended state observers in real time. The numerical simulations show that the proposed controller can not only achieve good dynamic and steady performance,but also have strong robustness against parameter disturbance and external disturbance.
