摘要
针对具有非线性?时变?非稳定等特点的柴油机电液调速系统提出变系数PID控制方法。该方法在充分利用传统PID控制器优点的基础上,利用误差变化的特点,采用变系数方法来构造PID控制器结构。仿真结果表明采用变系数PID控制方法进行控制,最大超调量、上升时间、峰值时间都达到比较满意的控制效果。
Variable coefficient PID is proposed for electro-hydraulic governor diesel engine which is a typical nonlinear,time-variation,unstable system.The method has improved PID control structure by making use of characteristic of error variable and applying variable coefficient method based on the advantage of classical PID control.Using variable coefficient PID control,the maximum overshoot,rise-time,peak time are fairly satisfied to have satisfying control effect.Simulation results show the effectiveness and feasibility of the proposed method.
