Abstract: Steering dynamic model of double motor coupling drive transmission for tracked vehicle has the features of MIMO, parameter-uncertainty and nonlinearity. The steering system is transformed into a forward speed control subsystem and a steering speed control subsystem by dynamic decoupling control algorithm.For the forward speed control subsystem, a robustness sliding mode control algorithm is proposed to converge the speed errors based on the desired speed and the current speed. For the steering speed control subsystem, a steering speed control algorithm is designed based on the fuzzy adaptive sliding-mode algorithm to ensure the tracking control of the reference steering speed. The steering tracking control is verified by real-time simulation system.The results show that the proposed control algorithm is effective.
