Abstract:
The paper proposes several concepts of integrators for sinusoidal signals. Parallel and series associations of the basic PI units using the stationary frame generalized integrators are used for current control of active power filters. Zero steady state error for the concerned current harmonics are realized, with reduced computation, under unbalanced utility or load conditions. Designing of the PI constants, digital realization of the generalized integrators, as well as compensation of the computation delay etc. are studied. Extensive test results from a 10 kW active power filter prototype are demonstrated.

Zhang, Richard S., "CONTROL OF SINGLE PHASE POWER CONVERTER IN D Q ROTATING COORDINATES"
Inventors:
Zhang, Richard S.
Abstract:
Imaginary orthogonal circuit state variables are established to enable transformation of real circuit state variables of a single-phase converter or the zero-sequence circuit of a three-phase converter from stationary coordinates to DQ rotating coordinates, thereby transforming the sinusoidal steady-state operating point of the real circuit into a DC operating point. A control provides the imaginary circuit state variables in a shifted queue comprising memory blocks for storing quarter-cycle shifted real circuit variables. Control of the converter is thus implemented in rotating DQ coordinates to achieve a theoretically infinite control loop gain at the fundamental frequency.
