神經網絡控制器在軟開關中的應用

摘要：在軟開關諧振功率變換器系統中，由于增加了諧振元件以及系統本身存在的嚴重的非線性和時變不確定性等特點，極大地影響了系統輸出電壓的動態響應性能。針對這一問題，本文提出了一種新的控制策略，將基于PID的神經網絡控制器用于脈寬調制型的軟開關諧振功率變換器中，提高了系統的動態響應性能。這種控制器是一種新型的誤差前向反饋神經網絡，將神經網絡和PID控制規律融為一體。 敘詞：軟開關 神經網絡 控制 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.
