Abstract:
In this proposed work a control of permanent magnet synchronous motor by using an artificial neural network and the motor is supplied by the voltage source inverter. The inverter gate pulses are controlled by using an artificial neural network. In the proposed system, the speed of the PMSM and the inverter output power are regulated. The system is based on the single artificial neuron which in turn minimizes complexity and computational burden requirements. The maximum power factor is obtained. The ANN based controller precisely and accurately follows command speed and also provides variable speed operation of the motor. This method of using artificial neural network reduces the output current ripples and motor torque ripples hence increases the efficiency. The performance of the proposed system and drive efficiency is verified by simulation results.
