| 摘 要： | 基于单位反馈控制结构,提出了离散域中对于时滞反向响应过程的直接设计新方法.该方法分析了反向响应系统控制器输出的振铃问题,给出期望闭环传递函数,并由此推出数字控制器的结构;通过分析设计参数,给出控制器单一调节参数的整定规则和获得更好控制器输出的参数选取方法.通过对一高阶的时滞反向响应过程进行仿真实验比较,结果验证了所提出的方法在抑制振铃方面具有较为明显的优势.

| Abstract: | This paper developed a new direct digital design method for inverse response process with time delay.The ringing problem in digital control for this kind of process was discussed,then a concrete form of the desired closed-loop transfer function was proposed,based on which the structure of the digital controller was obtained.Moreover,the robust stability of the proposed closed-loop system was analyzed,and correspondingly the tuning method of the single parameter was given.By simulation and comparison tests on a high-order inverse response process with time delay,the superiority of the proposed method was demonstrated at the aspects of achievable system performance and ringing elimination. |
