Distributed-logic-control is an independent parallel inverter control technique. The strategy to restrain circulating currents based on distributed-logical-control is researched in the paper. The conventional method by power regulation to restrain the circulating current is affected by the parallel impedance and has such disadvantages in the response speed and harmonic component of circulating current...
The traditional PID control strategy which is realized in digital method canpsilat achieve better performance than that in analog control. The reason was analyzed why the digital process influences the digital controlled PWM inverterpsilas performance in this paper. One is the process of the zero-order hold. Another one is one-step-delay control which is usually adopted in digital control. Three aspects...
The repetitive control technology is a high cost-performance waveform control technology widely used in the control of inverter. Compensator as the key parts of repetitive controller is usually adopted as the combination of notch filter with second-order filter. The process of designing and debugging of the repetitive controller, which needs more experiences, is very tedious. In this paper, FIR (finite...
