Extended Kalman Filter (EKF) was applied to permanent magnet synchronous motor (PMSM) position sensorless control in this paper, and this algorithm was simulated with Matlab/Simulink, and finally this algorithm was realized in the system with a TMS320F2812 controller. Both the simulation and experimental results proved the effectiveness of this algorithm, as well as higher speed,location identification...
This paper built the adjustable current model which uses the PMSM itself as a reference model with the parameter of speed of revolution adjustable. The self-adaptive law based on Popov hyperstability theory was deduced. The control scheme of PMSM Sensorless control technology based on MRAS was built. The control technology was simulated with Matlab/Simulink software. As the results of the simulation...
