This paper presents a new mathematical model for the pneumatic driving 6-DOF parallel robot controlled by pulse-width-modulation. The models not only overcome discontinuity of switching solenoid valve, but also change discontinuous and non-affine form into a canonical affine form. Then a sliding mode controller with fuzzy tuning is designed based on sliding mode theory and fuzzy theory and implemented on the pneumatic driving 6-DOF parallel robot position servo controlling system. The effectiveness of the controlling approach proposed here is validated by simulation data, which shows its capability of restraining the serious load coupling disturbance among channels and improving the trajectory tracking precision.

Abstract Due to large torque and quick response of electric motor, the traction wheels of battery electric vehicle (BEV) are easy to slip during the initial phase of starting. In this paper, an acceleration slip regulation approach based on sliding mode control algorithm is proposed to prevent the wheel slip of BEV. The traction wheel slip ratio is used as the control parameter, and a sliding mode controller is deduced from it. A fuzzy algorithm is employed to revise the switch function of sliding mode controller. After stability and robustness analysis, the sliding mode controller is validated by dynamic simulation of BEV. The sliding mode control law is transferred into vehicle control unit and is veried by road tests, the results of which show that the sliding mode controller is a good candidate to prevent the wheel slip.
