Problems solved by technology

[0004] The control deflection angle of the existing maglev platform is small, generally within 1°, which cannot meet the requirements for large-angle attitude compensation
In addition, most of the magnetic levitation platforms are levitated by nonlinear magnetic resistance magnetic bearings, which restricts the improvement of stable control accuracy and control bandwidth.

Abstract

The invention discloses a Lorentz inertial stable platform, which is composed of two parts: a mover system and a stator system. Sub-skeleton, inner mover retaining ring; the stator system mainly includes: spherical support ball seat, universal ball bearing, support column, base, stator frame, winding, epoxy resin glue, there is a spherical gas between the mover system and the stator system Gap. The Lorentz inertial stable platform of the present invention adopts a spherical support structure and has two stabilization modes of anti-rolling and maneuvering, and provides deflection control torque for the platform through a high-linear Lorentz bearing to ensure high stability and precision of the platform.

Description

technical field [0001] The invention relates to an inertial stabilized platform, in particular to a Lorentz inertial stabilized platform with large-angle deflection, high-precision rapid attitude stabilization, and high control bandwidth, which is especially suitable for attitude compensation of loads such as vehicles, ships, and aircraft. occasions. Background technique [0002] When the vehicle is running, the body shakes due to the rough road surface, which will cause the load on the vehicle to shake and cause the load posture to be unstable. Ships are affected by wind and waves during navigation, which interferes with the pointing accuracy of the stabilized aiming device on the ship and reduces the aiming accuracy. Under the action of windy weather, the high-altitude camera will deflect the lens, resulting in blurred imaging, so it is necessary to compensate the attitude of the payload. Existing inertial stabilization devices such as multi-axis turntables and swing tab...
