In order to improve the synchronizing control performance of hydraulic support test-bed,the adaptive sliding mode method based on fuzzy theory and sliding mode control was presented,and the master-slave synchronizing control characteristics were analyzed.The working principle and theoretical model of the hydraulic support test-bed were analyzed;the simulation model was established based on AMESim-MATLAB,and the synchronizing dynamic characteristics of the hydraulic support test-bed based on adaptive sliding mode control and fuzzy PID control were compared and analyzed.The results show that the synchronizing control characteristic controlled by adaptive sliding mode has more better tracking performance and steady state performance than that of the system controlled by fuzzy PID,which means that the adaptive sliding mode can be used for the synchronizing control of hydraulic support testbed.
