Design of Controllers by Indices of Precision and Speed. III. Control-Stable Multidimensional Plants

Abstract

A method to design controllers satisfying the requirements on precision and speed of each controlled variable was proposed. Additionally, a way was indicated to attain the given radius of stability margins simultaneously for physical input and output of the control plant at opening the closed-loop system by individual loops. Solution of the problem relied on the diagonal dominance of the transfer matrix of the closed-loop system—from external perturbation to the controlled variable—provided by the controller.
