Abstract

This paper studies output tracking control of three-phase grid-connected systems with parameter uncertainties. An output feedback model reference adaptive control (MRAC) scheme is employed to achieve three main goals: (i) the asymptotic output tracking of a time-varying reference signal, (ii) the asymptotic rejection of a practical class of unknown high-order harmonic signal disturbances, and (iii) a large reduction of signal measurements for control implementation. Control design conditions are verified for the PV system model, and the MRAC based disturbance rejection scheme is derived. Desired system performance is verified by simulation results. This study shows potential advantages of using adaptive control techniques for PV inverter systems.
