Voltage Frequency Ratio Control Method of the Cycloconverter Based on the GSO Algorithm

In order to keep the flux constant when asynchronous motor is running under load, especially light a Glowworm swarm optimization (GSO) algorithm proposed control voltage frequency ratio of cycloconverter. Based on analysis two variable theory cycloconverter and working principle cycloconverter, self-control method by adaptive fuzzy backstepping sliding mode proposed. process, GSO BFA are integrated optimize process controller, an selection strategy adopted ensure step size firefly improve accuracy algorithm. The experimental results show that optimal voltage-frequency switched between online continuous range small enough, speed stable, regulation always in state high force index. It shows has fast convergence good effect ring converter motor, it can load.
