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。
In order to improve PID control response with good anti-interference ability, this paper presents two system design method with pre-filter, which is a design method with a general pre-filter. The other is the design method with the shortest time filter. At the same time given the relevant design formula. Finally, the simulation example shows the effectiveness of this method, making the system response overshoot smaller, the response time to speed up. This method is therefore suitable for systems that require quick response.
