摘要：

This paper presents a direct active and reactive power control (DPC) for the three-phase grid connected dc/ac converters. The proposed DPC strategy employs an adaptive nonlinear control scheme to directly calculate the required converter's control voltage so as to eliminate the instantaneous errors of active and reactive powers without involving any rotating coordinate transformations. The control is based on adaptive input-output feedback linearization control (AIOFLC) . With an appropriate Lyapunov function, the control law and the estimation laws for inductance and resistance of filter and line are achieved. Using space vector pulse width modulation (SV-PWM) a fixed switching frequency is achieved which simplifies harmonic design of ac filter. Simulation results show the capability of the proposed AIOFLC in direct active and reactive power control with uncertainties in filter/line impedance.
