A Design Method of Disturbance Accommodating MRACS for Linear Unknown Systems

Abstract

In this paper, a design method of a model reference adaptive control system (MRACS) is presented for linear continuous single-input single-output plants in the presence of disturbanes.
It is assumed that the disturbances are expressed as the solutions of linear differential equations with unknown coefficients. Examples of such disturbances are stepwise, sinusoidal and exponential ones, including the sum of them. The proposed MRACS also works as a disturbance accommodating control system.
The boundedness of all signals in the MRACS is proved, which assures the convergence of the output error to zero.
Computer simulations are presented to illustrate the effectiveness of the proposed method.
