Identification of plant model of linear induction motors for a traction system intended for use in a high-performance controller.

A linear induction motor (LIM) is suitable for use in trains. The motor can be used in both wheel-suspended and contact-less types such as the Linear Metro and HSST trains in Japan. The LIM has end winding as well as asymmetrical winding. The end effect is a major problem in the LIM, and it makes the analysis, design, and control of motors difficult. This paper describes a method that combines numerical analysis and the equivalent circuit for the LIM in order to design a high-performance controller for the LIM that includes the end effect. A sample basic field-oriented control scheme that is based on the plant model is applied to the LIM in order to check the control performance. The theory of rotary induction motors is used for verification. © 2012 Wiley Periodicals, Inc. Electr Eng Jpn, 179(2): 44-54, 2012; Published online in Wiley Online Library ().
