A novel design and implementation of programmed PWM inverters to eliminate selected harmonics are presented in this paper. Switching patterns without low-order harmonics can be obtained by numerical techniques. Equal-area switching angles as initial values in numerical computation can guarantee the convergence of solving nonlinear equations. A well-designed circuit to generate switching patterns for...
This paper presents a sliding mode controller that uses a fuzzy logic to achieve a robust tracking of nonlinear systems. Sliding-mode control (SMC) is a robust control method, but does suffer chattering problem around the sliding surface. The pulse-width modulation (PWM) inverter uses SMC with a fuzzified sliding surface, and thus a low total harmonic distortion (THD) sinusoidal voltage in the inverter...
