摘　　要：目前节能液压泵站控制系统效率不高,为使其具有很好的抗干扰能力,使系统快速到达稳定状态,以伺服电机驱动内啮合齿轮泵为基础,设计出模糊PID的控制器,通过Simulink软件建立系统仿真模型,对系统进行不同性质类型的信号激励。进行仿真分析,比较无控制时,PID控制下和自整定模糊PID控制下的响应曲线。根据曲线可以知道,PID与自整定模糊PID控制下的响应曲线响应的速度都比较快,但是自整定模糊PID的效果更加的明显,稳定性比较好,取得的控制效果较为理想。At present, the efficiency of energy-saving hydraulic pump station control system is low. In orderto have a good anti-jamming capability and reach a steady state quickly, we base on servo motor driveninternal gear pump, designing a fuzzy PID controller and using simulink software establishing a systemsimulation model, giving the system different type signals, carrying on the simulation analysis. Comparingthe curves of uncontrolled response curve, PID control, self-tuning fuzzy PID control.According to thecurves, we can know response speed of the PID and self-tuning fuzzy PID control is faster, but the effect ofself-tuning fuzzy PID is more obvious, the stability is better, so the control effect is more ideal.
