accurate and correct performance of controller in cruise control systems is important. hence, in such systems, controller should optimize itself against noise and probable changes in system dynamic. as a matter of fact, in this article three approaches have been conducted to-ward this purpose: mit, direct estimation and indirect estimation. these approaches are used as controllers to track refe...

In this paper, the model predictive control (MPC) technique has been used to control the speed of the linear induction motor (LIM) drive. The mathematical model of the LIM has been described in the stationary frame. The longitudinal end effects of the linear induction motor are taken into account as external load.The concept of field orientation is used to decouple the mover speed from the seco...

Maglev transportation system is become a hot topic for researchers because of the distinctive advantages, such as frictionless motion, low power consumption, less noise, and being environmentally friendly. The maglev system’s performance gets sufficiently influenced by control method magnetic levitation dynamic performance, which critical component system. Magnetic Levitation System (MLS) group...

Abstract Dynamical systems, for instance in model predictive control, often contain unknown parameters, which must be determined during system operation. Online, or on-the-fly, parameter identification methods are therefore necessary. The challenge of online is that one continuously estimate parameters as experimental data becomes available. existing techniques the context time-dependent partia...

Senseless induction motor drives are widely used in industry for their reliability and flexibility, particularly in hostile environment. However, the performance of many of previously developed observer based speed sensors in very low speeds of IM drives was not satisfactory. In this paper we present two types of MRAS based speed estimators, one based on the rotor flux and the other based on th...
