摘要

A novel speed sensorless estimation and controller for asynchronous motor derives are proposed in this paper based on adaptive fuzzy neural network (FNN). The performance of the proposed adaptive FNN speed controller is evaluated for a wide range of operating conditions for asynchronous motor. These include startup, step changes in reference speed, unknown load torque and parameters variations. Obtained results show that the proposed ANN provides a very satisfactory speed estimation under the above mentioned operation conditions and also the sensorless adaptive FNN speed controller can achieve very robust and satisfactory performance and could be used to get the desired performance levels.
