Shanghai Baosteel Group, Sanghai 201900, China) Abstract: Tradtional voltage model of synchronous motor vector control system exists pure integral drift and so the initial value uncertainty. Some of the improved voltage model not only become more complicated, but also bring some negative factors. This paper introduces a flux observation scheme with a double integrator closed-loop, which is a Phase-Locked-Loop(PLL) essentially. It is introduced as a synchronous motor flux-gas chain observation modelthe novel voltage model, which not only can suppress the two problems of traditional voltage model, but also is simple in structure, easy to implement. Besides, it can be used for initial orientation for a synchronous motor. The simulation results are verified. Key words: synchronous motor; flux-gas observer; the novel voltage model; initial orientation; simulation 1 引言 [9][10]
