Abstract :
Four back-propagation training method for an offline neural network is compared in this paper. The neural network is designed to estimate the speed of an induction motor in a sensorless vector control system. In first step, four different training algorithms are used to train the neural network. Each training algorithm is tested with up to 35 neurons with fixed number of training iterations. The number of neurons that results in least training error is specified. Next, the number of training iterations is increased and the training algorithm with least amount of error is specified. The training algorithms are also examined with same number of neurons and learning iterations. Finally the training algorithm with least error and best convergence is used to estimate an induction motor vector control rotor speed
