Adaptive fuzzy PI controller, of which input is error e and error variety ratio ec, adjusts PI parameters itself in line according to e and ec in different time, and can overcome system performance reducing caused by variety of controlled object parameters and various non-linear uncertain disturbances, so it possesses better robustness and dynamic performance. Repetitive controller correct voltage cycle by cycle using disturbances repetitive characteristic, therefore high quality output voltage waveform is obtained, as well as well stable output and definite robustness.
模糊自整定PI控制器以误差e和误差变化率ec作为输入,根据不同时刻的e和ec对PI参数进行在线自调整,能克服被控对象参数发生变化或各种非线性不确定扰动对系统性能产生的影响,具有较好的鲁棒性和动静态性能;重复控制器利用扰动的重复特点逐周期地修正输出电压,保证系统高品质的输出,使系统具有良好的稳态性能和鲁棒性。
