| 摘 要： | 系统的动态性能指标主要有上升时间和超调量,基于这两个指标,该文提出一种数字控制方法,目的是减少控制参数。其基本思想是将系统的阶跃响应划分为多个区域,在不同的区域实时调整控制器的控制量,从而实现控制效果的整体最优。文中给出了控制策略和仿真控制结果,与数字PID相比,该方法只需要整定两个控制参数,它们有明确的物理意义。仿真结果表明该控制方法具有参数整定简单、容易使用、具有一定的自适应性,可获得满意的控制效果。

| Abstract: | The dynamic performance indicators of system there are settling time and overshoot.Based on these two performance,the paper bring forward a digital control method,the purpose is to reduce control arameter.The basic idea is the system step response is divided into more area,in different regions,control variables of controller is adjusted in real-time,so as to achieve the overall optimal control effect.In the paper,the control strategy and simulation control results is given.Compared with PID,the method only ... |
