摘　　要：针对传统PI调节器对交流控制系统会产生静态误差和动态调节能力弱的问题,基于伺服控制系统中的直流调节器转交流调节器的理论,将一种新型交流调节器引入到逆变电源控制系统的调节器环节,对实际工程应用中高增益频带过窄问题进行了分析,并介绍了改进措施和参数选取依据。通过设计基于该交流调节器的400 Hz单相逆变器的实验,验证了采用该方法得到的交流调节器可消除静态误差并具有快速的动态调节特性。A scheme is introduced to overcome the steady-state errors and the defect of dynamic regulating resulting from the direct use of the conventional PI regulator to AC signal.Based on the theory of servo control system that DC regulators can be converted into AC regulators,and a new AC regulator is adopted to the control system design of inverter. The improved measure for small bandwidth of high gain and the measure for select AC regulator parameters are proposed.The superior performance of achieving zero steady-state error and dynamic regulating are improved through theoretical analysis and experiments that the AC regulator apply into a 400 Hz inverter.
