In this book, speed control of a sensorless three phase induction motor is to be carried out using Predictive Current control (PCC) technique and space vector PWM. Hardware complexity of a motor drive can be reduced by estimating controls rather than measuring using sensors. In this, the corresponding sensors are to be eliminated so that the system becomes more robust. The PCC is based on a closed loop observer, which is insensitive to parameter variations. This closed loop observer calculates the required state variables over wide frequency range. This technique is more reliable even at very ...
In this book, speed control of a sensorless three phase induction motor is to be carried out using Predictive Current control (PCC) technique and space vector PWM. Hardware complexity of a motor drive can be reduced by estimating controls rather than measuring using sensors. In this, the corresponding sensors are to be eliminated so that the system becomes more robust. The PCC is based on a closed loop observer, which is insensitive to parameter variations. This closed loop observer calculates the required state variables over wide frequency range. This technique is more reliable even at very low frequency due to its insensitive nature against changes of motor parameters. Further, a Space Vector Pulse Width Modulation (SVPWM) voltage source inverter is to be used to feed the induction motor rather than SPWM. The drive system with proposed adaptive mechanism is to be simulated by MATLAB/SIMULINK for the verification of the performance of the technique.
