说明：  利用四缸火花点火发动机模型，实践基于dSPACE 实时仿真系统的具体实验方法， 判断控制器模型的优劣。其中包括基于MATLAB/Simulink 的闭环离线仿真实验, 创建ControlDesk 试验界面，完成应用程序的编译、连接，代码的生成及下载，调整PI 参数进行实时仿真实验。
(The use of four-cylinder spark ignition engine model, and practice the system based on dSPACE real-time simulation of specific experimental methods to determine the merits of the controller model. Including those based on MATLAB/Simulink simulation of the closed-loop off-line, create ControlDesk test interface, complete the application to compile, link, code generation and download, adjust the PI parameters in real-time simulation experiments.)
