基于状态空间的PWM逆变器数字PI双环控制技术研究
Research on the state space based digital PI dual loop control for PWM inverters
摘要
Abstract
The practical application of digital control , including dual loop digital control technique with instantaneous voltage and current feedback, as well as the feature of sinusoidal wave pulse width modulation (PWM) inverters, were mainly studied .Based on the establishment of state space model for the inverter control system , a dual loop digital control strategy ( the inner loop is for inductor current and the out loop is for output voltage ) was proposed with output feed forward .After direct discretization , the control system ’ s parameters were calculated by a pole as-signment method .The simulation waveforms under various conditions were presented .Both the simulations and the experiments showed that the proposed technique was simple and feasible , which can meet all the performance re-quirements of the inverter power source perfectly .关键词
