发布时间:2018-11-03 19:00
【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。
[Abstract]:At present, the efficiency of the control system of the energy-saving hydraulic pump station is not high. In order to make it have very good anti-interference ability and to make the system reach the stable state quickly, the fuzzy PID controller is designed based on the servo motor driving the internal meshing gear pump. The simulation model of the system is established by Simulink software, and the signal excitation of different properties is carried out. The response curves under PID control and self tuning fuzzy PID control are compared. According to the curve, the response speed of the response curve under the control of PID and self-tuning fuzzy PID is faster, but the effect of self-tuning fuzzy PID is more obvious, the stability is better, and the control effect is better.
