Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a three-phase inverter control method based on an improved artificial bee colony algorithm. Background technique [0002] The inverter is a converter that can convert direct current into constant frequency and constant voltage or frequency modulation and voltage regulation alternating current, and is an extremely important device in the power industry. The output waveform of the inverter has a lot to do with the control parameters, how to select the control parameters of the inverter is the hot spot of current research. The traditional manual tuning method relies on human experience, and its performance is average. Relay feedback requires oscillation information, and some systems do not allow oscillation to occur. The parameter setting using swarm intelligence algorithm does not require the operator to have a lot of manual experience, takes less time, and has a good appl...
