N2 - A new design method of multiresonant controller based on desired loop gain performance is proposed herein. Resonant controllers are one of the highest performance alternatives for AC system control. All of the methodologies to design multiresonant controller are based on parallel connection to the nominal controller, which involves complex calculations in attempt to design control system aided by Bode diagram. The proposed control scheme is based on series harmonic compensators, aiming the tracking of sinusoidal reference signals with zero steady-state error and the rejection of harmonic components of the output voltage. It is easy to implement and can be extended to be applied to various dynamic models. Then, the proposed control strategy is applied to an industrial DC-AC power inverter to demonstrate the potentials of multiply resonant controllers for sinusoidal tracking and harmonic rejection under both linear and nonlinear loading conditions. Performances of proposed methodology have been verified through simulation and real time experimental results.
