Modeling and energy saving control for common DC bus AC drive system based on hybrid Petri nets
摘要
Abstract
This paper introduces the hybrid system theory and establishes a common DC bus AC drive system hybrid Petri nets model and a motor power model based on the analysis of the system operation process. On this basis an energy saving control algorithm based on matching theory is proposed, namely the motor state adjusting algorithm which gets fuzzy pair of energy consumption state excitation and feedback state excitation through changing the random operation state in the controllable period of motor state. The results of simulation on DC bus power adopting this method show that it can effectively adjust and control the motor state, make the motor in energy consumption state absorb the electrical energy regenerated by motor in braking mode to a large extent,thus can reduce the DC bus power fluctuation and improve the system performance.This work is supported by National Natural Science Foundation of China (No. 51007056).关键词
