According to the analysis of simulation curves and the contrast between pid controller with disturbance feedforward compensation and fuzzy controller, it can be concluded that the new method of control not only has better robustness to the disturbance and varying parameter, but also has quick response and simple realization applying to the system with strict demand on the range of export parameter under variational condition 通过对仿真曲线的分析并与干扰前馈pid控制及模糊控制相比较,可以看出这种新的算法对干扰及参数摄动的鲁棒性强、响应快速且实现简单,尤其适用于工程上在变工况情况下对输出参数变化范围要求较高的系统。
