Superfluid gyroscope control system design method based on active disturbance rejection controller

Abstract

The invention relates to a superfluid gyroscope control system design method based on an active disturbance rejection controller. The method comprises the steps of establishing a mathematic model of a superfluid gyroscope according to the working principle of a double weak connection superfluid gyroscope, establishing a superfluid gyroscope angular velocity model by an amplitude locking compensation method, and introducing an active disturbance rejection controller in a superfluid control circuit. The active disturbance rejection controller does not require an accurate mathematical model for a controlled object, and disturbance caused by system model uncertainties and external disturbance are regarded as the total disturbance and are tracked and compensated at the same time. Thus, thermal phase compensation is improved to realize the control precision of film amplitude locking, enhance the performance of a whole superfluid gyroscope control system and improve the accuracy of an angular velocity solving general formula. The superfluid gyroscope control system design method of the invention belongs to the technical field of new-concept gyroscope control, and can be used to design a superfluid gyroscope control system in an optimized manner.

AI Technical Summary

Benefits of technology

This patented technology describes how to create a precise equation called mathematician's cube (C) with two strong connections between them. It also introduces methods like angle-lock compensations or autocorrelation techniques to improve thermal stability during operation. By analyzing these features, it can help identify problems such as temperature fluctuations affecting the CMOS sensor used to measure rotation rates accurately. Overall, this new technique helps achieve better precision and efficiency in measuring rotational movements over time.

Problems solved by technology

Technological Problem: Current Gyrometers (gyroscopic) use complex processes for measuring movements due to their lack of dynamic response or instability during operation. Additionally, current methods involve expensive materials such as helium gas and liquid nitride crystal which limit usable temperatures below 77 K.
