摘要:
对重复控制的理论,特别是模型不精确情况下的控制器设计问题进行了研究,给出了适用于恒压恒频逆变电源的重复控制器,提高了逆变电源在非线性负载情况下的输出电压品质.文中分析了重复控制器对谐波的抑制机理; 从系统极点分布规律入手,推导出控制器与受控对象之间的最佳关系; 基于对消的思想,给出了采用部分对消的重复控制器设计方法,并在控制器中引入了特殊的FIR函数,提高了系统的稳定性.最后,通过实验对新的设计法进行了验证.实验表明,采用新的控制器,逆变电源输出波形的谐波含量降到了0.446%,误差收敛速度也大大提高.
Abstract:
The theory of repetitive control has been studied, and extra work has been done on design method of the repetitive controller(RC)under inaccurate model. A new controller is provided for constant voltage constant frequency(CVCF)inverter, thus high quality of waveform can be obtained under nonlinear load. The principle of RC is described. Then, the optimal relation between controller and plant is analyzed from the viewpoint of pole placement. According to the principle of cancellation, the design method of limited cancellation is presented. To improve the robust of system, a special FIR filter is adopted in controller. At last, new controller has been validated by the experiment. The total harmonic distortion of output waveform is only 0.446%; the error convergence is faster than before.
