The Hydraulic-Driven Fan Speed Control System Research Based on Fuzzy PID

Aiming at the problem of high power consumption and low energy utilization rate of hydraulic driven fan cooling system of armored vehicle, the hydraulic control system is improved, and the corresponding mathematical model is established. The corresponding fuzzy PID controller was designed, and the simulation experiment was carried out to simulate the influence of the load torque and the speed of the engine on the fan speed. The results show that it can better adapt to the fan load torque and engine speed changes, and it has good tracking effect, which means that it can effectively meet the requirements of armored vehicle fan speed precise control.
