Research on Sensorless Control of Synchronous Reluctance Motor Based on High Frequency Signal Injection
Synchronous reluctance motor is a special synchronous motor with simple,durable structure and low cost,which has attracted more and more attention in recent years.The sensorless control technology of rotating high-frequency voltage injection method was applied to synchronous reluctance motor,and the posi-tion identification strategy of synchronous reluctance motor without band-pass filter was studied to simplify the control algorithm,reduce the position identification error and the operation pressure of processor.In the ex-periment,fundamental voltage and high-frequency voltage are injected separately in odd and even cycles to fully utilize the experimental power supply capacity,and in the experiment,fundamental voltage and high-frequency voltage were injected separately in odd and even cycles to fully utilize the experimental power sup-ply capacity.The simulation model was built on Matlab/Simulink environment.Besides,the hardware test platform of 1.2kW prototype was built.The simulation and experimental results both verify the effectiveness and accuracy of the simplified sensorless vector control algorithm.
