Abstract This paper proposes a multiple resonant based reference feedforward adaptive voltage control for three-phase inverters. The state-space model is established based on complex variables. Then, the proposed voltage controller includes two control parts: power control input and signal control input. The former improvesdynamic performance using state feedback and reference feedforward. A dynamic adaptive gain of the reference feedforward is defined as the signal control input, and the integral resonant controller is used to achieve no static error control. The rule of parameter variation is discussed by the root locus method to improve the dynamic performance. The proposed control strategy is a new type of multiple resonance control structure, and a new adaptive control idea is given. Besides, the proposed control method has excellent voltage regulation performance, including fast transient response, zero steady-state error, and low total harmonic distortion. The experimental results verify the proposed control scheme.

Key words： Inverter control adaptive control multiple resonant controller complex variable
