Abstract:This paper introduces a master-slave control system of hydraulic driven live working robot. Start with a brief description of the whole system, and adopt hydraulic drive way. Then put forward the idea that divide the live working robot control system into master control system and slave control system, the two sub-control systems adopt microprocessor TMS320 F2812.Finally, study the algorithm of the control system and propose a closed-loop control scheme depending on the fuzzy PID. Then make simulation of the control system by matlab, and the results prove that this is a valuable control scheme.
