Abstract

The invention provides a controllable pendulum based biaxial horizontal stabilized platform and a control method thereof, relating to a gyroscope free horizontal stabilized platform and a control method thereof. The biaxial horizontal stabilized platform comprises a mechanical device and a controller, wherein the mechanical device comprises a controllable pendulum system A, a controllable pendulum system B, a platform body, an outer frame, a control motor A, a control motor B and a pedestal. The biaxial horizontal stabilized platform overcomes the defects that the traditional biaxial horizontal stabilized platform adopts a gyroscope which has high cost and causes principle error by gyroscopic drift, and the like. A local horizontal platform can be realized by adopting the controllable pendulum systems with sensitivity to a local vertical line instead of a gyroscope, so that the horizontal platform has the advantages of simple structure, low cost, high sensitivity and the like.

Description

technical field [0001] The invention belongs to the fields of control and inertial navigation, and in particular relates to a two-axis horizontal stable platform (without gyro stable platform) based on a controllable pendulum system and a control method thereof. Background technique [0002] At present, the most widely used stable platform system is the gyro-stabilized platform. The motion angle of the table body relative to the inertial space is sensed by the gyroscope, and the angle is compensated by the closed-loop control torque motor, so as to overcome the influence of the carrier motion and ensure the local level of the table body. However, high-precision gyroscopes are complicated in technology, high in cost, large in size and weight, and have irregular random constant value drift, and the error accumulates over time. The existing gyro-free platform uses at least 12 accelerometers, and the angular motion information synthesis algorithm is immature, and the control imp...
