Shaft Sensor-less FOC Control of an Induction Motor Using Neural Estimators
Peter Girovský, Jaroslav Timko · 2012
The paper deals with a shaft sensor-less field oriented control structure for an induction motor based on neural network estimators. The first part presents the theoretical knowledge. The second part presents the simulation and results of designing neural estimators for observing the magnetic flux and the motor angular speed for induction motor field oriented control in MATLAB-Simulink. Controllers for simulation of shaft sensor-less field oriented control have been designed by state space method. An achieved simulation result of the neural angular speed estimator has been verified by system of AC converter - induction motor by Real-Time system.
