Abstract： In order to solve the multi-DC motors' synchronization control in field of process automation，with DC-motor synchronization control as the research object， the mathematical model of the control system was established from the parameters of the DC-Motor，the synchronization control system based on the traditional PID control method and its corresponding problems were analyzed. Then a fuzzy-PID controller was designed through the combination of fuzzy and PID control. Numerical simulation results show the good robustness，fast response and negligible error in the system，which can greatly suffice for the requirement of high precision of the system. And the developed experimental platform for this system is also verified with qualified results．
