Noise behavior improvement of adaptive control systems with a filtering strategy

In many control designs, noise tolerance is an important goal because of the robustness property of the designed controller. In this paper, we propose a filtering strategy for the transient and specially noise behavior performance improvement of model reference adaptive control (MRAC) for continuous time single-input single-output (SISO) systems with linear time varying (LTV) plant parameters. The controller to be applied is linear periodic controller; In fact, we apply filtered signals to the plant and controller instead of initial signals. Simulation results are presented to indicate the improvement in performance that can be achieved.
