Abstract

The invention discloses an inertia stabilizing device based on acceleration feedback and feed-forward and a control method thereof. The inertia stabilizing device comprises an accelerometer, a gyroscope, a turntable, a base and a servo controller. The feedback and feed-forward combined control is adopted in the control method. The control method comprises the following steps that a feedback stabilizing loop includes an internal acceleration loop and an external gyroscope loop, wherein an acceleration feedback signal is measured by the accelerometer; an acceleration feed-forward signal is supplied by the accelerometer mounted on the base, and the acceleration feed-forward signal passes through a low-pass filter and is guided to a node for the acceleration feedback input. The inertia stabilizing device has the advantages of simple structure, excellent robustness and high stabilization and is beneficial to engineering realization.

Description

technical field [0001] The invention relates to the technical field of inertial stabilization, in particular to an inertial stabilization device based on acceleration feedback and feedforward and a control method thereof, which can be used for stabilization of a high-precision inertial platform. Background technique [0002] Inertial stabilization platform is widely used in aviation, aerospace, navigation and other fields, and is an indispensable key technology in modern life. Its main function is to isolate external interference and maintain stability in the inertial space. The inertial stabilization control technology mainly uses the gyroscope as the key device, but due to the limitations of mechanical structure, sensors and other conditions, it is difficult to improve the closed-loop bandwidth of the gyroscope. In many harsh environments, such as severe wind moment, foundation disturbance moment, etc., the system based on gyro stabilization cannot well meet the engineeri...
