Speed Control of FSTP Inverter Fed Induction Motor Drive with a Neural Network Control
In this paper, the speed control of an induction motor using Four Switch Three Phase Inverter (FSTPI) and neural network is proposed. The proposed paper has been carried out by the design and implementation of inverter and control circuit. The four switch three phase inverter is used because of low cost, lesser switching losses and reduced complexity of control algorithm and interfacing circuits. The control circuit was developed by designing a three layered feed forward neural network estimator which estimates rotor flux, unit vectors and torque by taking voltage and current reference from machine terminals.
