说明：  整个软件是MATLAB环境下的控制系统仿真，用户输入控制系统前项通道传递函数和反馈通道传递函数以及性能指标，绘制出校正前开环系统的BODE图，并给出稳定裕量和对应的频率。 判断该用哪种校正装置。给出校正装置的传递函数，在一幅图上显示校正后系统的BODE图。给出校正后系统的性能指标。
(The software is the MATLAB environment control system simulation, user input control system before the entry channel transfer function and the feedback channel transfer function and performance indicators, drawing out the correction before the open-loop system of the BODE diagram, and gives a stable margin and the corresponding frequency of . Determine the correct device to use which. Calibration device transfer function is given in a map display system BODE diagram after correction. Corrected performance of the system are given index.)
