摘　　要：为解决存在建模误差以及外部扰动状态下电子节气门的优化控制问题,提出了一种基于线性二次型的最优滑模控制方法。首先,根据电子节气门工作原理建立其非线性数学模型,并推导出误差状态方程。而后,以输出误差和输入控制量为性能指标,根据模型线性部分设计了优化控制器。进而,对模型非线性部分进行了分析,基于滑模控制理论设计了补偿控制器。最后,基于Matlab/Simulink平台进行对比数值仿真。仿真结果表明,所提控制方法能够有效克服外部干扰以及模型参数带来的不确定性,实现电子节气门实际开度对目标开度的精确跟踪,且控制器输出以及跟踪误差较传统控制方法均有一定程度的改善。In order to solve the problem of optimal control of electronic throttle with modeling error and external disturbance,an optimal sliding mode control method based on linear quadratic form is proposed.Firstly,according to the working principle of electronic throttle,the nonlinear mathematical model is established,and the error state equation is derived.Then,the optimal controller is designed according to the linear part of the model.Then,the nonlinear part of the model is analyzedand a compensation controller is designed based on sliding mode control theory.Finally,the comparative numerical simulation is carried out based on MATLAB/Simulink platform.The simulation results show that the proposed control method can effectively overcome the external interference and the uncertainty caused by the model parameters,and realize the accurate tracking of the actual electronic throttle opening to the target opening,and the output and tracking error of the controller are improved to a certain extent compared with the traditional control methods.
