Embodiment Construction

[0079] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0080] An adaptive fuzzy control method for micro gyroscopes based on dead zone compensation, including the following parts

[0081] 1. Establishment of non-dimensional dynamic equations of micro gyroscope

[0082] A micro-vibration gyroscope generally consists of three components: a mass supported by an elastic material, an electrostatic drive device, and a sensing device. The main function of the electrostatic drive circuit is to drive and maintain the constant amplitude of the vibration of the micro-vibration gyroscope; the sensing circuit is used to sense the position and speed of the mass. The micro gyroscope can be simplified as a damped vibration system composed of a mass block and a spring. figure 1 A simplified model of the microvibration gyroscope in Cartesian coordinates is shown. For micro gyroscopes, it can be conside...

Abstract

The invention discloses a self-adaptation fuzzy control method for a micro gyroscope based on dead zone compensation, wherein a designed self-adaptation fuzzy compensator performs compensation to nonlinear influence of the dead zone before actual control input, the self-adaptation fuzzy compensator is composed of a fuzzy logic system, estimates a dead zone boundary in real time and adjusts the parameter of the compensator in an self-adaptation manner; a robust control term ensures that the system has excellent robustness for external disturbance and model uncertainty, the system has a steady closed loop, and the tracking error is converged to zero quickly. The self-adaptation fuzzy compensator can be widely used for the control of a micro gyroscope, so that the stability and reliability of the system are improved, and the compensator has the industrial utilization value.

Description

technical field [0001] The invention relates to a control system of a micro gyroscope, in particular to an adaptive fuzzy control method for a micro gyroscope based on dead zone compensation. Background technique [0002] Microgyroscopes are the most commonly used sensors for measuring angular velocity in many applications such as navigation, guidance, and control stability. A microgyroscope is a device that uses the Coriolis force (i.e., the deflection force of the Earth's rotation) to transfer energy from one axis to another. The traditional mode of operation lacks the ability to drive the gyroscope from one mode to a known oscillation. Motion, while the detected Coriolis acceleration is coupled to the sensing mode of vibration, which is perpendicular to the driving mode, and the response of the vibration sensing mode provides information about the practical angular velocity. Due to the existence of errors in the manufacturing process and the influence of the ambient temp...
