Problems solved by technology

[0009] These three points are the main reasons for the technical bottleneck of the current gyroscope rebalancing loop design, and the direct consequence is that the mathematical model of the gyroscope is unknown, which leads to a great blindness in the design of the control loop, and the loop debugging process is cumbersome and inefficient. It is difficult to guarantee the performance of the loop, and even affect the output accuracy of the gyroscope

Description

technical field [0001] The invention relates to a gyroscope, in particular to a method and a device for generating gyroscope hardware. Background technique [0002] A gyroscope is a sensor that measures the angular velocity of a vehicle. As an important inertial navigation component, it is widely used in navigation, aviation, aerospace and other fields. With the development of unmanned aerial vehicles and tactical missiles, higher requirements are put forward for the dynamic and static performance and output accuracy of the gyroscope. In order to enable the gyroscope to obtain a larger measurement range in a smaller linear working range, the gyroscope must work in a locking mode or a force feedback mode, that is, a control loop is required to adjust the working state of the gyroscope. The control accuracy and effectiveness of this control loop are directly related to the dynamic and static characteristics and output accuracy of the gyroscope, and occupy an important positi...
