Abstract
This paper represents the control strategy for the speed control of induction motor without using any feedback position sensor. The system uses speed, torque and current loops to estimate the actual speed of the motor and to generate the six pulses according to the error signal between the reference speed and the estimated speed. Six pulses are given to the real time inverter, which is supplying AC source to the motor. The change in characteristics of the pulses changes the speed of the induction motor. The hardware setup is made by interfacing between the MATLAB simulink model and the field sensors and the inverter. The proposed system is simulated in the MATLAB/Simulink, also the system is dumped into the space System and Arduino Board to generate the required six pulses for the six bridge inverter. These pulses are given to the inverter. Thus, the speed of the system is controlled without using the position sensor. This system is mainly proposed to reduce the cost of the system by eliminating the use of position feedback sensor by the current and voltage sensors. This system is having high accuracy, less cost, less complexity and weight of the system and it is highly reliable and efficient system. © 2006-2016 Asian Research Publishing Network (ARPN).
