摘要

本文通过仿真和相对的总方差性能测量表明,在控制滞后占主导地位的一阶时滞对象时,适当滤波的PID控制相对于滤波的PI控制可以显著提高环路性能。通过分析采用改进的多重实主导极方法设计的高阶低通滤波器的影响,表明在滤波PI控制的情况下,使用阶数为n >1的滤波器可能是有益的。对于PID控制来说,最有趣的性能可能是在n >2时实现的。

Filter choice for an effective measurement noise attenuation in PI and PID controllers
This paper shows by simulation and by a relative total variance performance measures that in control of lag dominated first order time delayed plants appropriately filtered PID control may significantly increase the loop performance with respect to filtered PI control. By analyzing the impact of higher order low pass filters designed by a modified multiple real dominant pole approach it shows that in the case of filtered PI control it may be beneficial to use a filter order n > 1. For the PID control the most interesting performance may be achieved for n > 2.
