摘　　要：针对电子节气门(ET)系统非线性特性对节流阀控制精度的影响,提出了一种鲁棒自适应无抖振滑模控制(ACFSM)方法。该控制方法考虑了ET系统非线性和参数不确定性的影响,引入了遗传算法(GA)优化了ACFSM控制器的控制参数获得了平滑的控制信号,结合所设计的自适应控制律减轻了不确定性的影响。为验证所提控制方法的有效性,通过实验表明ASCFM控制器不仅在闭环系统响应中不存在抖振现象,而且可以很好地保持良好的瞬态和稳态跟踪性能。通过对比表明ASCFM控制器在跟踪性能上优于ASM控制器,尤其在节流阀遇到外部干扰时,所提出的ASCFM控制器具有较强的鲁棒性。Aiming at the influence of nonlinear characteristics of electronic throttle(ET)system on throttle control accuracy,a ro-bust adaptive chattering free sliding mode control(ACFSM)method is proposed.The control method considers the influence of ET system nonlinearity and parameter uncertainty,introduces genetic algorithm(GA),optimizes the control parameters of ACF‐SM controller,obtains smooth control signal,and reduces the influence of uncertainty combined with the designed adaptive con-trol law.In order to verify the effectiveness of the proposed control method,experiments show that ACFSM controller not only has no chattering in the response of the closed-loop system,but also can maintain good transient and steady-state tracking perfor-mance.The comparison shows that ACFSM controller is better than ASM controller in tracking performance,especially when the throttle valve encounters external interference,the proposed ACFSM controller has strong robustness.
