A simple feed forward fuzzy direct torque control of DSP based induction motor drive

In this paper, a simple method is presented for direct torque compensation by fuzzy based feed-forward control technique, which provides advance speed control for three-phase induction motor. To achieve better dynamic performance of induction motor cascade design is implemented with direct torque control (DTC) technique with two different methods, conventional and fuzzy logic are used to compare the better performance of the control system. Fuzzy logic controller (FLC) provides better and smooth speed control. The speed control technique is implemented using a new generation digital signal processor (DSP) TMS320F28335 with a high sampling rate to make it possible to achieve good dynamics. The Result shows the supremacy of the FLC in controlling three-phase induction motor with DTC technique.
