针对汽车电子节气门位置伺服系统高精度、高动态品质的控制目标,并考虑到系统中存在的本征非线性和参数摄动及外部扰动的不确定性,研究了指数型终端滑模控制器设计。为使系统处于滑动模式时有限时间收敛至平衡点,滑模面选取为指数型终端超曲面;趋近率采用终端趋近率,进一步提高系统的快速性。控制器的有效性通过与现有滑模控制方法作用效果的对比得到验证,仿真结果表明本文设计的控制器快速性好,抗干扰能力强。

By aiming at the control target of high accuracy high dynamic quality and considering the intrinsic nonlinear parameter perturbation and external disturbance uncertainties an exponential terminal sliding mode controller is designed for automobile electronic throttle position servo system.In order to render the system to convergence to the equilibrium point in finite time when the system is in sliding mode an exponential terminal hypersurface is selected as the sliding surface.Terminal reaching law is choosed as the reaching law which further improves the rapidity of system.The validity of the designed controller is verified through compari?son with the existing method of sliding mode control effect.The results show that the controller designed in this paper guarantee the rapidity and strong anti?interference ability of the system.
