Discrete Model Reference Adaptive Systems with Measurement Noise

A digital computer simulation study is presented for a class of discrete model reference adaptive systems designed using Lyapunov’s direct method. Plant output measurements are assumed to contain uniformly distributed additive noise. It is shown that the design works well even when such noise is relatively extreme. A new result is presented pertaining to improving the convergence properties of these systems. This result is obtained by modifying the dynamic characteristics of the augmented error equation.
