Three-phase SPWM inverter system based on fuzzy control

Fuzzy control (FC) technology based based on knowledge inference is one of the efficient strategies for a system with nonlinear or imprecise model. This paper has applied FC technology to a three-phase SPWM inverter system for seeking better control strategies. Proceeding with fuzzy logic, fuzzy rule and fuzzy inference, a kind of configuration of a fuzzy control system for a three-phase SPWM inverter has been introduced, which can be used to solve the nonlinear or imprecise problems of power electronic equipment control. The paper has established the foundation for further applications of FC technology in wider domains. The FC system is verified to be feasible by simulation and experiment.
