Abstract

The invention provides an inertia rate composite stable control system, wherein a servo controller is electrically connected with a servo turntable, the bottom seat of the servo turntable is connected on a base platform, a turning direction of the servo turntable is parallel to a sensing shaft of a first angle rate gyroscope and a sensing shaft of a second angel rate gyroscope; the first angle rate gyroscope is arranged on the base platform, and is used for generating a disturbing signal of the base platform and outputting a feedforward stable control signal; a speed measurement machine is connected with a rotating shaft of a motor through a connecting shaft; the speed measurement machine is used for obtaining a motor rotating angular speed signal; the second angle rate gyroscope is arranged on load and is used for obtaining an angular rate signal of the servo turntable to achieve a feedback stable loop; the servo controller receives and utilizes a speed given signal, a top feedback signal, a top angular rate feedforward signal and a speed measurement signal of the speed measurement machine to achieve a speed control loop, the feedback stable loop, feedforward stable control, to generate a speed output control signal, to output the speed output control signal to the motor, and to achieve closed-loop control.

Description

technical field [0001] The invention relates to the field of inertial stability control, in particular to a composite stability control system realized by using an inertial rate sensor, which is mainly used for suppressing the vibration of a platform. Background technique [0002] The main function of inertial stabilization technology is to isolate external interference and maintain stability in inertial space, which is a very important key technology. The current stabilization technology is generally based on the gyro, and the control methods are mainly divided into two methods: rate feedback (direct) stabilization and rate feedforward (indirect) stabilization. For example, literatures (Inertially Stabilized Platform Technology. IEEE control system magazine, 2008; Direct Versus Indirect Line of Sight (LOS) Stabilization. IEEE transactions on control systems technology, 2003) have made corresponding reports. The ability of rate feedback stabilization is closely related to r...
