“…However, if the central axes of the drive coils and sleeve do not coincide, the radial forces around the drive coils are not balanced, and there exists a transverse force due to the asymmetry. This force is called the restoring force, and it is the fundamental tool for the analysis of the dynamic motion of the coil drives in the transverse(radial) direction [16]. A 3D FEM analysis presented in [4] shows that the restoring force acting on the moving part is satisfactory to levitate and guide the moving part and deal with the low-damping problem, which is one of the most important dynamic stability problems that occur in the maglev systems.…”

“…5(b) shows the movement of the drive coils in the direction of the y-axis. This will cause the y components of the radial forces at points A and C, also points B and D, to be unequal [16], but due to the restoring force that exists between two noncoaxial circular coils, the moving part is placed in the center again [15]. In order to calculate the equivalent force between sleeve and drive coils, instead of integrating the force on the differential element over the entire loop of the drive coils, it is better to distinguish the two force elements in each half of the drive coils circle.…”

Nowadays, with the increase of population, demand for efficient public transportation systems has increased. Magnetic levitation (maglev) trains are one of the best choices for the future. There are three separated systems in a classical magnetic train to achieve desirable performance. Hence, several control systems and sensors are essential for train operation. Accordingly, the classical maglev trains include complex structures, and they are so expensive. This paper presents the design, optimization, and control of a combined magnetic train structure with the integrated performance of suspension and guidance and a complementary propulsion system. These combined topologies provide a simple design, more convenient movement, and reduce construction and operation costs.

Problem of calculation of distribution of magnetic field induction in clearance of tubular linear induction motor (TLIM) is considered. Mathematical model is represented by Fredholm integral equations of second kind for complexes of electric field strength and density of coupled magnetization currents at interface of environments. Algorithm of calculation of distribution of magnetic field induction in TLIM clearance has been developed. Dependence of magnetic field induction in motor clearance on value of pole division is investigated. There is area of optimum pole pitch. Reliability of results of calculations on mathematical model is confirmed by their comparison with results obtained on physical model. Calculated dependence of induction on thickness of runner's iron circuit also has extreme character. Given model can be used at design stage of TLIM. Model allows calculating its optimal geometric dimensions based on criterion of maximum induction in motor clearance, taking into account physical properties of applied materials.

“…Linear Motor transmission systems are widely applied to provide directed straight motions in which, mechanical actuators are eliminated, resulting in better performance of motion systems. Generally, Polysolenoid Linear Motor (PLM) has a durable structure, operations according to electromagnetic phenomenon with principles as shown in [1][2][3][4][5][6][7][8][9][10][11][12] and various applications such as CNC Lathe [13], sliding door [14]. Without the need of any gear box for motion transformation, the PLM system becomes sensitive due to external impacts such as frictional force, endeffect, changed load and non-sine of flux.…”

The Polysolenoid Linear Motor (PLM) have been playing a crucial role in many industrial aspects due to its functions, in which a straight motion is provided directly without mediate mechanical actuators. Recently, with several commons on mathematic model, some control methods for PLM based on Rotational Motor have been applied, but position, velocity and current constraints which are important in real systems have been ignored. In this paper, position tracking control problem for PLM was considered under state-independent disturbances via min-max model predictive control. The proposed controller forces tracking position errors converge to small region of origin and satisfies state including position, velocity and currents constraints. Further, a numerical simulation was implemented to validate the performance of the proposed controller.
