Novel approach of speed control of PMSM drive using neural network controller

The current paper shows the modeling, controller design and simulation of Permanent Magnet Synchronous Motor (PMSM) drive. As the paper deals with use of neural network methods to implement control of PMSM hence two control methods are used-For the inner loop current control the Hysteresis current controller is used and for the purpose of outer loop speed control the PI controller is used. The conventional Proportional-Integral (PI) controller is used in industries because of its robustness but when the dynamics of system changes with time or with certain operating conditions, the PID controller can't be used. The solution that alters this situation is to use Artificial Neural Network (ANN) which provides the field-oriented control scheme of the PMSM drive. The simulation results show the validity of ANN based PMSM drive to ensure robustness towards load and parameter variations.
