摘要针对三相逆变器控制,该文提出一种基于多重谐振控制器的参考值前馈自适应控制。首先,基于复变量建立状态空间模型,并设计状态反馈控制,作为功率控制输入,用以改善系统动态响应。同时,设计参考值动态前馈控制,定义动态前馈增益为信号控制输入,创新性地利用积分谐振控制器,自适应调节动态前馈增益,即信号控制输入,从而达到无静差控制。基于根轨迹方法分析整定多重谐振控制参数。该文提出的控制方法是一种新型的多重谐振控制结构,给出一种新的自适应控制思路,且所提控制方法具有良好的电压调节能力,如快速暂态响应、稳态误差小及总谐波畸变率低等。最后,通过实验验证了所提多谐振自适应控制的有效性。

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
