【摘要】 为了改进PID控制响应同时具有良好的抗干扰能力,本文提出了两种带有前置滤波器的系统设计法,这就是一种具有一般前置滤波器的设计法。另一种是具有最短时间滤波器的设计法。同时给出了有关的设计公式。最后通过仿真例子来说明这一方法的有效性,使系统的响应超调量较小,响应时间加快。因而这一方法适合于要求快速响应的系统。更多还原

【Abstract】 In this paper, two methods for designing a PID control system with a pre-filterare provided so as to improve its response and anti-disturbance capacity. The first is one with a general pre-filter, and the other is one with a deadbeatpre-filter. Related design formulae are given systematically. Finally, the effectivenessof the latter is shown in a modeling example. The process response overshot is smallerand the response time is much shorter. This method is suitable for systems whichrequire fast response.更多还原
