Problems solved by technology
However, the micromechanical movement mainly relies on the swing swimming and rotating swimming generated by these external fields to drive the movement of the device, which can only be used in viscous liquids, and cannot meet the detection and transportation of gas media or mixed media scenes. For silt work, there are fewer applicable application scenarios and a narrower scope

The invention discloses a two-dimensional plane suspension motion method and device based on force unbalance driving, which relate to the technical field of magnetic levitation. The method comprises the steps of: detecting a two-dimensional plane position signal of a floater through a position sensor on the basis of external magnetic field driving and determining the position of the floater, enabling a current sensor to feed back excitation winding current information of the electromagnetic driver, automatically adjusting the current of the electromagnetic driver in combination with a PID control algorithm, changing the external magnetic field intensity and achieving stable suspension of the floater, and enabling a micro-control unit to be combined with the PID control algorithm to automatically adjust the current value in the excitation winding according to the set target position, enabling the floater to reach a new balance position through interpolation operation, and realizing suspension motion at any position in a two-dimensional plane controllable area. The invention also discloses a set of device, which comprises supporting legs, a base, an intermediate plate, a floater, anelectromagnetic driver, a position sensor, a mounting plate, a connecting plate, a current sensor, a power amplifier and a micro-control unit and is used for realizing two-dimensional plane motion control of a suspended object.
Description
technical field [0001] The invention relates to the technical field of two-dimensional plane motion control of suspended objects, in particular to a device and method for two-dimensional plane suspension motion driven by force imbalance. Background technique [0002] Magnetic field drive technology is a high-tech that integrates many disciplines such as mechanical engineering, control engineering, and electrical engineering. Specifically, the magnetic field drive technology refers to the use of the electromagnetic force generated by the magnetic field to counteract the effect of gravity to suspend the object in the air without support and drive its movement. In the magnetic levitation system, the object is suspended in the air without support against gravity, and there is no mechanical contact between the electromagnetic device and the suspended object, so there is no friction and mechanical wear in the magnetic levitation system. Therefore, magnetic levitation technology h...
