Implementation of a fast terminal sliding mode controller for direct thrust control systems

This paper presents a new methodology to implement a permanent magnet linear synchronous motor. The proposed method is a combination way which is combined the fast terminal sliding mode with the direct thrust control method. The intended advantage of the proposed method is that the chattering phenomenon can be reduced and/or removed. To our knowledge, the inherent flux linkage problems of permanent magnet linear synchronous motors did not seem to be handled by the pioneer contributions. For overcoming the problems, a new estimator algorithm is used to get the accurate flux linkage value. Finally, some experimental results are met as expected.
