薛定宇教授编写的MATLAB控制分析工具包Ctrllab 该工具包解压后，通过MATLAB修改路径后，可进行时域、频域、复域的各种分析，比如bode图，奈氏图等等。

Description： CtrlLAB is a group of MATLAB functions which provide graphical interface to perform feedback system analysis and design tasks. The facilities provided by CtrlLAB are: a) model entering, including SIMULINK modeling b) model display c) system state space realisation d) model reduction using different algorithms e) system analysis in frequency, complex and time domain f) graphical display and figure editing and manipulation g) a matrix displayer and editor h) PID tuning and displaying facilities i) a great many controller design procedures are implemented CtrlLAB 3.0 is designed exclusively for use MATLAB version 5 and over. Some of the advanced facilities for MATLAB 5.2 have been reflected in CtrlLAB 3.0. CtrlLAB 3.0 requires the Control System Toolbox and Simulink for many of it's functions. For robust control problems, the Robust Control Toolbox is required.

matlab下的分数阶PID算法实现工具，可建模仿真系统，经过测试可以使用。

薛定宇教授 ctrllab工具箱3.0；PID参数仿真用。 使用方法：1）解压，并在matlab下导入路径；2）在命令窗口执行ctrllab即可。
