摘要
研究了一种基于双环控制和重复控制的逆变器控制技术,该方案在电流环和瞬时电压环之外附加了一个重复控制环。在实现输出电压解耦和扰动电流补偿后,根据无差拍原理设计的双环控制器使逆变器达到了很快的动态响应速度;位于外层的重复控制器则提高了稳态精度。该方案在一台基于 DSP TMS320F240控制系统的 PWM 逆变器上得到验证。
A inverter control technology based on dual-loop control plus repetitive control is studied. The scheme added a repetitive control outer loop exccept to intorporate a current loop with an instantaneous voltage loop. After realizing output voltage decoupling and the load disturbance compensation the dual-loop controller based on deadbeat theory sends the inverter to achieve very fast dynamic response. The repetitive control outer loop improve the steady-state performance. The scheme is proved on a PWM inverter whose control system based on DSP TMS320F240.
