Multivariable Adaptive Harmonic Steady-State Control for Rejection of Sinusoidal Disturbances Acting on an Unknown System

摘要

This paper presents an adaptive harmonic steady-state (AHSS) controller,which addresses the problem of rejecting sinusoids with known frequencies thatact on a completely unknown multi-input multi-output linear time-invariantsystem. We analyze the stability and closed-loop performance of AHSS forsingle-input single-output systems. In this case, we show that AHSSasymptotically rejects disturbances.
