Problems solved by technology

[0003] At present, the automatic gain control is mainly used in the amplitude control system of the micromachined gyroscope. It cannot be compatible with rapidity. If the system responds quickly, the system overshoot will become larger. If the system overshoot is desired to be small, then the system's rapidity will be reduced.

Embodiment Construction

[0061]The present invention will be further described in conjunction with the examples.

[0062]In this embodiment, iffigure 1 The medium micromechanical gyro is the control object, and the frequency control circuit uses the phase-locked loop to provide a sinusoidal signal for the micromechanical gyro to make the gyro are simple. The amplitude control circuit uses self-immunity control to stabilize the amplitude of the micro-mechanical gyro output signal. Both loops are closed-loop control.

[0063]In this embodiment, iffigure 2 The medium frequency control circuit shown is used by the phase-locked loop to provide a sinusoidal drive signal in which the lock phase loop loop includes: 1, the phase difference is used to determine the phase difference of the micromechanical gyro output signal to the input signal. 2, loop filter, according to the correction phase output error, output control voltage, control the output frequency of the voltage controlled oscillator. 3, voltage control oscillat...

Abstract

A micromechanical gyroscope amplitude control system based on ADRC comprises a micromechanical gyroscope, the micromechanical gyroscope is controlled through a frequency control loop and an amplitude control loop, a phase-locked loop is used in the frequency control loop for providing sine driving signals for the micromechanical gyroscope, and the gyroscope is made to conduct simple harmonic vibration; active disturbance rejection control is used in the amplitude control loop to stabilize the amplitude of an output signal of the micromechanical gyroscope; and the two loops adopt closed-loop control. According to the invention, the amplitude stability and stability of the output signal of the micromechanical gyroscope are improved.

Description

Technical field[0001]The present invention relates to the field of micro-mechanical gyro, and more particularly to an ADRC-based micromechanical gyke value control system.Background technique[0002]Micromechanical gyro is a core component of inertial navigation systems and inertial instruments, possessed and important status in strategic weapons, and applications in tactical weapons are also increasingly wide, and various systems and equipment consisting of gyro are extensive. For navigation sectors such as navigation, aerospace, land and weapons.[0003]Automatic gain control is mainly used in the stage micromechanical gyro value control system, which is a control method based on the PID control method. The method will produce over-tuning, over-tuning due to the relationship between the proportional coefficients during the control amplitude. If the rapidity is not part, if the system is prompted, the system is super-tone will become large. If you want the system to become smaller, the...
