摘 要：The electronic throttle determines the intake volume of the automobile engine,which directly affects the fuel efficiency and gas emissions of the *** the control performance of the automobile electronic throttle plays an important role in energy saving and emission ***,due to multiple nonlinearities,i.e.,friction,spring,gear backlash and a series of external disturbances,the accurate control of the electronic throttle is a challenging *** this paper,a chattering-free discrete-time fast terminal sliding mode control law is designed for electronic throttle systems based on disturbance *** the proposed algorithm,a nonsmooth function is introduced to replace the switching function in the traditional discrete-time sliding mode *** alleviates the chattering problem of control ***,the fast terminal sliding mode surface is applied in this algorithm to replace the linear sliding mode *** dynamic response and higher position tracking accuracy can be ***,the disturbance compensation is added to the control law to eliminate the influence caused by disturbances,which improves the disturbance rejection ***,simulation comparisons with the traditional discrete-time sliding mode control are presented to validate the effectiveness and feasibility of the proposed control approach.
