Research on Sliding Mode Control Strategy of Demotion Robot's Working Equipment by Means of ADAMS and Simulink

Based on the working principle of the electrohydraulic proportional control system of the working device of the demolition robot, the co-simulation model of the system is established by means of ADAMS and MATLAB. The study of the dynamic characteristics of the system was done, with applying traditional PID control strategy and sliding mode variable structure control respectively, considering the change of the control object parameters caused by the pose change of the working device and the external disturbances. The co-simulation results show that the sliding mode variable structure control strategy has excellent dynamic performance, better robustness and faster response compared with traditional PID.
