A variable structure model reference adaptive control for plants with relative degree greater than one and unknown high frequency gain sign is proposed.A switching scheme is introduced based on a monitoring function designed for the first auxiliary error of the close loop system.It is shown that under the supervision of the monitoring function,the switching stops after at most a finite number of switchings and the tracking error converges to a residual set that can be made arbitrarily small by appropriately choosing some design parameters.
A variable structure model reference adaptive control for plants with relative degree greater than one and unknown high frequency gain sign is proposed. A switching scheme is introduced based on a monitoring function designed for the first auxiliary error of the close loop system. under the supervision of the monitoring function, the switching stops after at most a finite number of switchings and the tracking error converges to a residual set that can be made arbitrarily small by decentrations some design parameters.
