摘　　要：在工业过程控制中,传统PID控制方式用于较复杂被控对象时,在超调量与稳定性等方面都难以获得令人满意的结果。本论文以内模控制器作为研究对象,完成了内模控制器中低通滤波器的设计与Matlab仿真研究,得到了不同情形下的频率特性曲线,同时,通过与传统PID控制对比,对不同类型控制方式的特点进行了分析研究,得到了有意义的研究结论,对实际工业过程控制具有一定实用参考价值。In industrial process control,when PID control,a traditional control model was applied to some complicated controlled objects,usually control effect is not satisfied as good as expected.In this paper,by focusing study on internal model controller,design and Matlab simulation of the low-pass filter,a very important component in the internal model controller were completed.Amplitude and frequency characteristic curve were drawn under different cases.By compared with PID in controlling characteristics,meaningful conclusions were conducted which might be applicably valuable to industrial process control in practice.
