On the way to real time fuzzy control of a PWM source inverter with nonlinear loads

This paper presents a new approach for PWM voltage source inverter real time control, based on fuzzy logic. The special case of nonlinear loads is studied. From error and error variation measurements, a new control law is proposed to reduce the harmonic distortion and to provide a good fundamental regulation. The system architecture is described and the fuzzy control algorithm is implemented by offline calculated look-up tables in order to minimize time response. The simulation results are compared to other classical approaches in terms of static and dynamic performances. They show good results in spite of the coarse definition of the plant
