Take advantage of Matlab/Simulink designed welding mobile robot brushless DC motor system model which based on conventional PID controller、integral separation PID controller and fuzzyPID controller, then simulation study was carried on the model. The simulation results show that compared with conventional PID controller and integral separation PID controller, fuzzyPID has higher accuracy and better system dynamic and static characteristics, allowing the system to get better performance.
Key words: conventional PID; integral separation PID; fuzzyPID; Matlab/Simulink
