Embodiment Construction

[0037] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0038] as attached figure 1 Shown is a control block diagram of a narrow-band large-value disturbance suppression method based on an inertial loop, which includes the feedforward compensation loop, acceleration loop, speed loop, and position loop of the disturbance observer; the targeted disturbance suppression method and the traditional three-closed loop Combined with the control method, the narrow-band large-value disturbance is further suppressed in a targeted manner. The specific implementation steps of the method are as follows:

[0039] Step (1): Install gyroscopes and accelerometers on the two deflection axes of the control-stabilized platform to sense the angular velocity and angular acceleration of the two axes of the platform in inertial space, respectively. The sampling frequency of velocity and acceleration here is...

Abstract

The invention discloses a narrow-band large-value disturbance suppression method based on an inertial loop, which is used to solve the problem that a higher-precision stable control system cannot be satisfied when there is a narrow-band large-value external disturbance on a stable platform of a control system. This method proposes a narrow-band large-value disturbance suppression method based on the inertial loop on the basis of multiple closed-loop control. The present invention first proposes stability constraints on the design of the feedforward compensation controller starting from the system stability, and on the basis of ensuring the system stability, starts the design from the notch filter, and combines the method of the disturbance observer to propose a forward control method for the external narrow-band large-value disturbance. The design scheme of the feedback compensation controller finally achieves the purpose of effectively suppressing the external narrow-band large-value disturbance, ensuring the stability of the system and effectively improving the stability accuracy of the control system.

Description

technical field [0001] The invention belongs to the field of stability control, and in particular relates to a narrow-band large-value disturbance suppression method based on an inertial loop, which is mainly used to effectively suppress external narrow-band large-value disturbances and further improve the stability performance of motion platform stabilization equipment. Background technique [0002] In the control equipment, the stability accuracy of the system will be affected by external disturbances, such as ground vibration, vibration of the stable platform caused by perturbation caused by air flow. Especially for stabilization equipment installed on moving platforms such as airplanes, automobiles, ships, etc., the stabilization platform will be disturbed a lot due to the irregular movement of the installation carrier. In some specific cases, such as when the stable platform is on the moving platform, the external disturbance can be directly measured by the sensor, and ...
