Abstract :
According to the technical requirement of 11 kW permanent magnet synchronous motor (PMSM) which is used for elevator, this paper presents a position sensorless vector-control system based on model reference adaptive system (MRAS). The inverter-motor drive models are substituted for the decelerator-motor drive models in this drive system based on the digital signal processor (DSP) and using the TMS320LF2407 DSP controller. It fully utilizes the wealthy peripherals and high-speed calculation function of DSP, and uses the vector control method and MRAS strategy. The simulation and experimental results show that the whole control system is simple, feasible and effective
