Abstract :
Nonlinear output feedback controllers are derived to achieve active harmonic reduction at ac (alternating current) port current in PWM (Pulse-Width-Modulated) inverter with internal resistance in dc (direct current) port. The controller design is carried out on the basis of state averaged model which is a bilinear system. The control problems are treated as nonlinear H∞ output feedback control problems for the bilinear system via Lyapunov-based game theory approach. Convex programming technique gives concretely the controllers. Computer simulations show efficiency of the control system design approach.
