According to the performance requirements for an automatic support force control system of temporary support equipment in the mining process in roadway, this paper uses a comparative research method, and combines theoretical analysis and experimental study methods. It analyzes the principle of automatic support force control sys-tems in advance supporting equipment. The mathematical model of control object, an electro hydraulic servo valve and a hydraulic cylinder, was constructed, and a fuzzy-PID controller for automatic control of supporting force was designed. Through comparitive simulation, it was found that the fuzzy-PID control is better than the conventional PID control. An experiment was conducted on the simulation platform of the advance supporting equipment. From the experiment results, it can be seen that the fuzzy-PID based automatic control system of supporting force can work very well, and it has good response characteristic and stability.
