Abstract:
From conveyors to the high-speed MAGLEV vehicles, from knitting machines to the sophisticated
robotic systems, Linear Induction Motors (LIMs) have got a wide range of applications. They have got
all the potential to replace the age-old belt-pulley driven systems completely in the coming years. In
the present work, a flat, single sided, short primary LIM, which can be used as a linear propulsion
system, has been designed and the same has been fabricated. Thereafter PI controllers are designed to
implement the field oriented control scheme for use in variable speed drives. The whole system is
simulated in the SIMULINK environment of MATLAB and the simulation results are shown. Since
the PI controllers cannot handle model uncertainties and parameter variation effects, a robust
controller has also been designed. Implementation of the whole scheme is to be done using a DSP in
TMS320LF2407A platform. Dry run of the programs has already been done. The inverter is under
construction.
