Problems solved by technology

[0010] The belt pulley transmission system has a simple structure and cannot be combined at will. Because the life of the rubber belt and the reliability of the transmission method are poor, only the driving pulley provides power, so it is easy to determine the fault location after a failure; the structure of the roller transmission system is more complicated than that of the belt pulley transmission system. It can't be combined at will. The reliability of using rollers is average. Each roller has an independent power source. Once a failure occurs, it is difficult to determine the source of the failure and maintenance is more difficult. However, the system can transport heavier objects.

Embodiment

[0031] Structural principle of magnetic levitation planar motor

[0032] The moving-coil magnetic levitation planar motor in this embodiment consists of two parts: a stator and a float. Magnetic levitation planar motor structure such as figure 1 As shown, the float is a moving coil structure consisting of 4 coil groups. The coil set is composed of 3 coils. figure 1 The middle coil group and the configuration of the coils in the coil group are convenient to explain its working principle. In practical applications, the number and arrangement of the coil groups and the configuration of the coils in the coil group can be customized according to the suspension repulsion requirements. The two-dimensional Halbach type permanent magnet array can provide a three-dimensional distributed magnetic field. The two-dimensional Halbach magnetic array is composed of a main magnet and a secondary magnet. The main magnet is square, and the secondary magnet is rectangular. The magnetization dir...

Abstract

The present invention belongs to the fields of high-end equipment manufacturing and logistics. Specifically, it is a logistics device based on a magnetic levitation planar motor and its control method. Each magnetic levitation planar motor in the device is a unit module. Through any combination of modules It can meet the transportation requirements under different working conditions. Aiming at this new type of logistics device, the present invention proposes a method of controlling the displacement and attitude of the float by adopting self-adaptive contraction and backstepping control. This control method has faster response speed, stronger robustness, and stronger anti-disturbance ability.

Description

technical field [0001] The invention belongs to the fields of high-end equipment manufacturing and logistics, and specifically relates to a logistics device based on a magnetic levitation planar motor and a control method thereof. Background technique [0002] With the advancement of science and technology, road transportation, railway transportation, and air transportation are becoming more and more developed, and the transportation speed is getting faster and faster. People's lives have been closely connected by modern logistics. The important role of modern logistics in regional economic development has been increasingly recognized by people, and many provinces and cities have put the development of modern logistics on their agenda. Logistics modernization is closely related to economic development. It is expected that China's economy will maintain stable and rapid growth for a long period of time in the future, and the trend of connecting with the world economy will also...
