Adaptive sliding mode and model predictive control of linear variable reluctance motor

Linear motors is a class of motors which produces linear motion. In general we deal with rotational type motors. In these paper position control of linear motors is discussed. The linear motors are very much expensive and difficult to control. To deal with such problems a different type of linear motor is discussed here namely linear variable reluctance motor. Linear variable reluctance motor comprises the characters of linear synchronous and linear switched type motors. Linear variable reluctance motors is easy to control compared to linear motors. Another aspect of these paper is that the problems associated with conventional sliding mode. The major drawback of conventional sliding mode controller is that the system is sensitive to external disturbances prior reaching the sliding surface. Also the output position is affected by chattering when the system reach the sliding surface. To eliminate these two drawbacks here introduce a controller called adaptive sliding mode controller. Also here a comparison is made between sliding mode and model predictive controller.
