Abstract

In this paper, a robust adaptive scheme is presented for attenuating disturbances in a multi-input multioutput algebraic linear system with time delay and parametric uncertainties. By using a performance index analysis, a time-varying gain matrix is obtained that minimizes the performance index. It is shown that by augmenting the system with an asymptotically stable, strictly positive-real subsystem, the adaptive scheme results in asymptotic attenuation of bounded disturbances. Simulation results axe given for a multiinput, multi-output system in the presence of considerable parametric uncertainties and time delay which further confirm the analytical developments
