Linear induction motors are most widely used in high-pressure linear motor applications, where steady force ratings of nearly 25gms of acceleration and hundreds of pounds are required. LIM systems are more complex to develop because they require sophisticated control algorithms. At the time of service, these have strengthened attractional forces. The acceleration performance of EV, which affects a lot of performances of EV such as start-up, overtaking, driving safety, and ride comfort, has become increasingly popular in recent researches. An improved variable gain PID control algorithm to improve the acceleration performance is proposed in this paper. The results of simulation with Matlab/Simulink demonstrate the effectiveness of the.

Web. Nonlinear control of the squirrel induction motor is designed using sliding mode theory. The developed approach leads to the design of a sliding mode controller in order to linearize the behaviour of an induction motor. The second problem described in the paper is decoupling between two physical outputs: the rotor speed and the rotor flux modulus.

The Linear Induction Motor is similar in construction to a circular motor that has been opened out flat. The magnetic field now sweeps across the flat motor face instead of rotating. The stator generally consists of a multi phase winding in a laminated iron core. When energized from an AC supply a travelling wave magnetic field is produced. In the early years of the 20th century, when rotating electrical machines had become established and made to perform satisfactorily, it was realised that these machines could be made in a different form which would use or produce motion in a straight line, instead of the normal rotary motion.
