| 摘 要： | 在振动式微陀螺的工作过程中,输入角加速度的变化将导致驱动轴振动幅值的变化,从而降低微陀螺的测量精度.文章研究利用自动增益控制技术使微陀螺驱动轴振动幅值保持恒定的方法,提出了合适的MIT自适应控制律,并且利用Simulink仿真验证了该方法的正确性与可行性,仿真结果表明,自动增益控制在提高微陀螺的测量线性度方面有显著作用.

| Abstract: | For Micromachined Gyroscopes, the vibration amplitude in driving direction changes with the input angle velocity, thus the measuring precision is degraded. This paper presents the use of Auto Gain Control in keeping the vibration amplitude invariable for Micromachined Gyroscope. A proper MIT adaptive control law is worked out. Then the validity and feasibility of that law is checked by simulation. The results of simulation show that Auto Gain Control could improve the measure linearity of Micromachined gyroscope obviously. |
