Embodiment Construction
[0081] The present invention will be further described in detail below through the specific examples, the following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention with this.
[0082] Such as figure 1 As shown, the micro-gyroscope fractional-order adaptive fuzzy neural inversion terminal sliding mode control method includes the following steps:
[0083] 1. Establishment of the dimensionless dynamic equation mathematical model of the micro-gyroscope system
[0084] A general micromechanical vibrating gyroscope consists of three parts: a suspended mass supported by an elastic material, an electrostatic drive device, and a sensing device. It is simplified as a damped oscillation system composed of a mass block and a spring. For the z-axis micro-gyroscope, it can be considered that the mass block is restricted to move only in the x-y plane, but not along the z-axis, and only rotates around the z-axis.
