Modeling, Control and Simulation on Drive System of Hydraulic Drill

On the basis of a hydraulic drill impact principle, a drive's calculating method was established that of hydraulic drill, an electro- hydraulic principle was analged that of hydraulic drill with drive system. It puts forward a rational scheme of a drive control system of hydraulic drill with high-speed on/off valve. It introduces a newfuzzy PID control method by establishing a model and analyzing control strategy, and then carrig on the strict theory reasoning. Finally, this system is simulated in MATLAB, and the result of the simulation proves the superiority of the fuzzy PID controller. With all the conclusions mentioned above, it provides the theoretical basis and technical guidance for the drive system of hydraulic drill.
