| 摘 要： | 针对基于音圈电机的直驱阀系统中存在液动力负载扰动对系统的稳、动态性能有较大影响的问题,以及经典PID控制所存在的不足,在建立基于音圈电机的直驱阀系统数学模型的基础上,提出一种位置环/电流环的双闭环控制结构.位置环采用非线性PID(Nonlinear PID,NLPID)控制,给出了位置环模糊NLPID控制器的具体设计方...

| Abstract: | The hydrodynamic force disturbances in direct drive valve based on voice coil motor(VCM-DDV) have greater impact on system performance.There are some weaknesses in classic Proportion integration differentiation(PID)control.In this paper,a mathematical model of the VCM-DDV is established.A double-closed loop control structure composed of position loop and current loop is presented.A novel nonlinear PID(NLPID) control strategy is applied in position loop.Fuzzy control is used to achieve self-tuning of control... |
