Abstract
The authors propose real-time signal processing based on deadbeat control of a pulsewidth modulation (PWM) current inverter with parameter estimation for induction heating applications. The one-step-ahead controller strategy is used in deadbeat control with voltage and current sampling and in deadbeat control, with current sampling. The controllers' stability is analyzed by the discrete root locus method and the load parameters are estimated by the least squares method. A current-fed inverter of 4 kHz with a sampling time of 8.33 mu s is considered. Computer simulation results are presented.<>
