The speed control of Induction motor is done using the advance AI Technique methods. In this System the vector control scheme in the stator flux oriented reference frame is used for controlling the variable speed Induction motor. For this the conventional Speed PI controller and Current PI Controllers are tuned and the responses are observed. The Conventional Speed PI Controller is then replaced by the Fuzzy Logic Speed Controller to observe the various responses of the system. The fuzzy Logic Speed Controller is designed and tuned in such a way to obtain better and fast sped responses of the system. Simulation results reveal that the fuzzy-controller improves the performance of variable speed Induction Motor in terms of speed and Power factor

This paper presents the rotor flux and speed estimation of induction motor using a novel technique. The induction motor model in rotor reference frame is considered. Controllers used for sensor less control of the drive. The estimation technique works well and the sensor less speed control scheme can achieve fast transient response as good as that of the induction motor with sensors and at the same time maintain a wide speed control range.

Today induction motor requires a variable speed control to serve wide range of applications. The objective of this work is to control the position of a field oriented induction motor for a given reference input signal. This work addresses the design of a speed control scheme based on total sliding-mode control (TSMC) theory for a field-orientated induction motor (IM). The total sliding mode control comprises an equivalent control design and a robust control design. In this work the control strategy is derived in the sense of Lyapunov stability theorem such that the stable tracking performance can be ensured under the occurrence of system uncertainties. The salient feature of this control scheme is that the controlled system has a total sliding motion without a reaching phase. The work is been accomplished using Matlab/Simulink. In this work a comparison is been done for a fixed torque & change in torque (Change in motor parameter).
