ABSTRACT:
The present invention discloses a method and system for controlling a power supply by delivering stable output voltage independent of load. The control system includes a sensor for sensing a state variable, a fuzzy logic controller for generating a control action, and an actuator for regulating the power supply in accordance with the control action. The fuzzy logic controller generates a fuzzy logic knowledge base using low-level fuzzy logic controllers and a mode selector in one embodiment and a fuzzy logic proportional integral controller in another embodiment. The generated fuzzy logic knowledge base is compiled in a look-up table and is used to quickly and efficiently control a power supply device such as a resonant converter.
