应用MATLAB实现自动控制系统的频域法校正

Using MATLAB to Realize the Automatic Control System with Frequency Domain Method

利用MATLAB下的BODE图进行控制系统串联校正,可以进一步提高利用MATLAB平台下进行控制系统频域分析的能力,通过举例介绍在MATLAB平台上使用频域法进行系统串联校正的理论根据与操作方法 ,给出了用MATLAB进行串联超前校正设计的一般步骤,通过改变系统的开环波德图形状,使之具有满意的性能指标,对工程设计人员有一定的参考价值.

By using MATLAB to correct BODE diagram of control system m series, we can ennance me aDmty of analysis in the frequency domain of control system under the MATLAB platform, then illustrate theoretical tan- dem and operation method of correction system according to use of frequency-domain method in the MATLAB platform, giving the general steps in series ahead correction using MATLAB by changing the system＇s open-loop Bode plot shape, so as to have a satisfactory performance, which has some reference value for engineering design.
