“…This control strategy can provide the same performance as that achieved from a separately excited DC machine [5,6,7]. The implementation of vector control involves the rotor time constant, which may vary considerably over the operational range of the motor, mainly due to changes in rotor resistance with temperature.…”

-This paper deals with direct torque control of an induction motor (IM) with constant switching frequency. The desired torque is obtained from the speed controller which is designed using the IP controller. Decoupling control of torque and flux is developed based on the energy model of IM using the IP controller strategies. The desired d-axis and q-axis stator voltage components are obtained from the designed controller, which decouples torque and flux. The constant switching frequency can be applied using space-vector pulse width modulation, since the desired stator voltage can be known from the decoupling torque and flux controllers. In order to achieve stable operation of the proposed IP controllers, the gains of the controllers are chosen by setting the poles in negative (left) half of s-plane and by choosing the rising time for the response of the step function. The proposed controller was verified in simulations using Matlab/Simulink and results have proven excellent performance. It was found that the proposed IP controllers can provide excellent performance to track the desired torque and speed and to reject the disturbance of load.

“…To maintain the dynamic performance of the system, online tuning procedures are needed to compensate any change of the rotor time constant due to motor temperature variations. Different approaches have been presented in literature [5][6][7][8][9]. All of these approaches require additional sensors that were not strictly used in the original IFOC drive, thus, increasing cost and complexity.…”

Abstract-The design of high performance induction motor drives is a complex task, and the every day compelling requirements in energy efficiency and performance assumes the motivation on finding a more integrated solution on implementing induction motor control. The main subjects of this paper are two: to discuss the IFOC one-chip solution and to explore the development of simple graphical applications in order to operate this control in a simple and effective way. Experimental results are presented to illustrate the main points of our paper.
