Abstract:

A design scheme of variable structure model tracking controller using only input and output measurements is presented for a class of multi input and multi output (MIMO) uncertain model reference adaptive control (MRAC) systems with disturbances in  input channel. By introducing  the auxiliary signals and normalized signals with memory functions and appropr iate choice of controller parameters,the variable structure controller developed guarantees the global stability of the closed loop system, and the tracking error can be arbitrarily small.

Key words: Unmodeled dynamics, Disturbances in input channel, Variable structure control, Globally asymptotically stable
