Robustness and transient performance of adaptive decoupler for a class of multivariable systems

Abstract

A new adaptive decoupling controller for a class of multivariable systems is proposed in this paper. The method can realize decoupling in the steady state and in approximate dynamics. The unmodelled dynamics, bounded disturbances and remains of approximate decoupling are compensated for to improve the system characters. Robustness is established under the upper conditions. We also analyse the transient performance by the pole restriction method
