摘　　要：带前馈输入观测——状态反馈控制系统的设计过程,涉及带符号变量的矩阵方程组求解,其通解一般难于求出,国内外大多数文献只能用递推法求其前几个采样值。借助MATLAB符号数学工具箱的有关函数,直接进行带符号变量矩阵运算和方程组求解,得到其准确的通解,系统设计全过程由编制的M文件自动完成。仿真结果表明,提出的设计方法和求解过程是正确的。The CAD of an observer-state feedback control system with feed-forward input involves the solving of matrix equations with symbolic variables and finding its general solution is difficult, most of the literature at home and abroad can only be used recursive method to making his first few samples. In this paper, by using the relational functions in MATLAB symbolic math toolbox, the matrix operation with symbolic variables can be performed and the general solution of equations can accurately be obtained. The whole process of system design is automatically completed by pre-programmed M-files. Simulation results show that the proposed design method and solving process is correct.
