An adaptive multivariable DDC algorithm for the servo regulatory problem

This paper presents an adaptive multivariable DDC algorithm for the servo regulatory problem of a class of multivariable systems. An errorless d-step ahead prediction form of the open-loop system is first introduced. Then a trivial design step is proposed to achieve the prescribed overall matrix fractional description of the closed-loop system. The recursive multiple least-squares algorithm is suggested for the adaptive estimation of the regulator parameters. At the end digital and real-time analog simulation results are presented.
