摘要:在軟開關(guān)諧振功率變換器系統(tǒng)中,由于增加了諧振元件以及系統(tǒng)本身存在的嚴(yán)重的非線性和時(shí)變不確定性等特點(diǎn),極大地影響了系統(tǒng)輸出電壓的動(dòng)態(tài)響應(yīng)性能。針對(duì)這一問題,本文提出了一種新的控制策略,將基于PID的神經(jīng)網(wǎng)絡(luò)控制器用于脈寬調(diào)制型的軟開關(guān)諧振功率變換器中,提高了系統(tǒng)的動(dòng)態(tài)響應(yīng)性能。這種控制器是一種新型的誤差前向反饋神經(jīng)網(wǎng)絡(luò),將神經(jīng)網(wǎng)絡(luò)和PID控制規(guī)律融為一體。

Abstract:In resonanced soft switch converter system, on account of resonanced component and unlinearity and incertitude which consist in system, which influenced the dynamiced respond of output voltage seriousiy. In allusion to this problem,the text advanced a new control policy, used the nerve network controllerPID in resonanced power soft switch converter which based on pulse width modulate. By done this could enhance dynamiced respond of the system. The converter was a new error forward feedback nerve network which combined nerve network which PID controling rule.
