A new algorithm for finite spectrum assignment of multivariable systems with time delays
K. Watanabe, Kou Yamada, T. Okuyama, Kohei Takahashi · 2002
This paper presents a new algorithm for computing the feedback matrix of finite spectrum assignment of multivariable systems with time-delays under spectral controllability. The key is the Smith-form of the controllability matrix. That yields a weakly R-controllable system. The feedback matrix over rational functions in delay operator for a weakly R-controllable system is transformed to the feasible one with polynomials and finite Laplace transforms.
