基于自适应模糊PID的径向柱塞变量泵电液伺服控制

Electro-hydraulic servocontrol of radial variable displacement piston pump with adaptive fuzzy PID control

针对电液伺服控制径向柱塞变量泵变量机构,设计了自适应模糊PID控制器,并通过计算机仿真,再现了系统跟踪阶跃信号的系统响应.仿真结果表明,基于自适应模糊PID控制器的电液伺服控制径向柱塞变量泵具有良好的动态性能.

Aimed at the displacement varying mechanism of electro-hydraulic servocontrolling radial piston pump, an adaptive fuzzy PID controller was designed and simulated with computer. System response to step input was obtained. It is shown by this simulation that under the control with this controller, the electrohydraulic variable displacement radial piston pump exhibits quite fair dynamic characteristics.
