多变量自校正调节器算法的改进

Improvement of the Algorithm for Multivariable Self-tuning Regulator

介绍了把谱分解方法推广应用于多变量自校正调节器的算法，即为使系统的平方性能指标达最小，寻求闭环传递矩阵最佳分母阵Ｄｃ（Ｚ）时，运用谱分解方法，不仅避免通常采用的求解Ｒｉｃｃａｔｉ方程的途径，而且计算过程更为简捷，使之更有利于实际应用．

The spectral factorization is applied to the algorithm of the multivariable self-tuning regulator,i.e.to minimize the square performance function in order to seek the optimal denominator matrix Dc(z)of the transfer matrix of the closed loop system.It can not only avoid solving of the Riccati equation but also make calculation more simple and convenient.Therefor it is advantageous apply in engineering.
