摘要：
This paper proposes a novel discrete-time robust model reference adaptive controller based on a modified recursive least squares applied to grid-connected converter with LCL filter. This controller uses an input–output approach to reduce the number of sensors, and it is robust to additive and multiplicative unmodeled dynamics and sinusoidal disturbances. Experimental results are presented in order to verify the performance of proposed control strategy. © 2017, Brazilian Society for Automatics--SBA.
