摘要: 从工程应用角度出发,提出一种用H∞控制理论设计一类多变量系统的次优敏感性控制 器的工程设计方法,并证明了其可行性.该方法通过将系统矩阵化为对角占优,利用单独通道 设计思想将多变量系统转化为单变量系统的H∞最优敏感性控制器问题.文末给出了仿真实 例.Abstract: In this paper, a practical approach to the optimal sensitivity controller design for a class of multivariable system is developed using H∞ control theory from the engineering point of view the application. By transforming the system matrix into diagonally dominant form, the design problem for the multivariable system is solved by designing H∞ optimal sensitivity controllers for single variable systems via individual channel design. The validity of the approach is proved, and a simulation example is given.
