1、试设计串连校正装置，在同一窗口下分别绘制出校正前后的频域响应曲线，阶跃响应曲线，判断系统校正前后的稳定性；

2、设计串连校正装置，在同一窗口下绘制出校正前后的波特图进行验证，并在同一窗口下绘制校正前后系统的奈奎斯特图；

3、设计串联滞后超前校正装置，绘制出校正前后系统的伯德图；

4、设计串联校正装置使校正后的闭环系统的主导极点；

5、设计串联校正装置，维持原系统的闭环主导极点基本不变；

6、设计状态反馈阵。-And try to design concatenation correction device, were drawn in the same window, the frequency response curve before and after correction, the stability of the step response curve, determine the system before and after correction　design concatenation correction device, drawn in the same window Bode plots before and after a correction to verify, before and after correction system Nyquist diagram drawn in the same window　3 design series lag the leading correction device, drawn before and after correction system Bode plot　design series correction The closed-loop system in the device so that the corrected the dominant pole　design series correction device to maintain the original system closed-loop dominant pole is essentially the same　6, the design state feedback matrix.
