摘要
文中将目前逆变器输出波形控制技术分为基于周期的控制和瞬时值反馈控制。基于周期的控制是通过对误差的周期性补偿,实现稳态的无静差效果,主要包括重复控制和谐波反馈控制。瞬时值反馈控制利用快速检测,及时对逆变器的输出波形进行校正,主要包括瞬时值内环反馈控制、PID(单闭环)控制、双闭环控制、线性多变量状态反馈控制等。在对这些控制方法的特点作了相应的分析后,从波形控制的实际要求出发,提出了最有前途的方案。
The waveform control technology of inverter is classified into periodic control and instantaneous control in this paper. Periodic control, including repetitive control and harmonic wave feedback control, compensates the error periodically to promise no - error effect. Instantaneous control, including instantaneous inner- loop feedback control, PID control, dual- loop control, linear multiple state feedback control and so on, corrects the inverter output waveform in time by fast detection. Analyzed the characteristics of these methods, the paper proposed the optimum solution which is according to the object of actually request of waveform control.
