| 摘 要： | 简要介绍在多变量控制系统中有着广泛应用前景的INA设计技术及其MATLAB实现，INA法的基本思想是通过选择预补偿器使原系统的逆前向传递函数矩阵成为对角优势阵，从而实现各输入输出变量之间的基本解耦，在用逆乃圭斯特阵列法(INA法)把多输入多输出(MIMO)回路间严重关联的多变量系统设计问题转化为一组单变量系统设计问题的基础上；阐述了用MATLAB语言完成INA法设计的机辅设计步骤；借助MATLAB语言用INA法设计了一个三输入三输出控制系统，并对设计好的系统进行数字仿真，结果表明，所设计的系统可以稳定工作，各项指标均可满足工程要求。

| Abstract: | This paper briefly introduces INA method and MATLAB accomplishment, widely used in multivariable Frequency Domain Control System. The INA's basic idea is that, through selecting pro-(compensator,) inverse pro-transitive function matrix of previous system can be changed into diagonal preponderance matrix. Therefore, decoupling between each input and output will be realized. This paper states the accomplishing procedures of INA and computer assist design by means of changing the problem of MIMO system design into a group of SISO system design problem. With the help of MATLAB language and INA method, the control system of three input and three output is proposed. It is proved that the designed system can work properly, and each index can meet the needs of engineering. |
