Gyroscope01:02

Gyroscope

A gyroscope is defined as a spinning disk in which the axis of rotation is free to assume any orientation. When spinning, the orientation of the spin axis is unaffected by the orientation of the body that encloses it. The body or vehicle enclosing the gyroscope can be moved from place to place, while the orientation of the spin axis remains the same. This makes gyroscopes very useful in navigation, especially where magnetic compasses cannot be used, such as in crewed and crewless spacecraft,...
Gyroscope: Precession01:24

Gyroscope: Precession

Precession can be demonstrated effectively through a spinning top. If a spinning top is placed on a flat surface near the surface of the Earth at a vertical angle and is not spinning, it will fall over due to the force of gravity producing a torque acting on its center of mass. However, if the top is spinning on its axis, it precesses about the vertical direction, rather than topple over due to this torque. Precessional motion is a combination of a steady circular motion of the axis and the...

Area of Science:

  • MEMS (Micro-Electro-Mechanical Systems)
  • Inertial Navigation Systems
  • Sensor Technology

Background:

  • Silicon microgyroscopes (SMGs) are crucial for inertial navigation but suffer from mode coupling and temperature drift.
  • Existing designs often struggle with cross-talk between drive and sense modes, limiting performance.
  • Temperature variations significantly impact the zero bias stability of microgyroscopes.

Purpose of the Study:

  • To design and develop a miniature, vacuum-packaged silicon microgyroscope (SMG) with a symmetrical and decoupled structure.
  • To enhance resonant stability and disturbance rejection capabilities.
  • To experimentally characterize and compensate for temperature effects on the SMG's zero bias.

Main Methods:

  • A symmetrical and decoupled structural design was implemented to prevent drive-sense mode coupling.
  • A self-oscillating closed-loop circuit with automatic gain control (AGC) was used for drive mode stabilization.
  • Dual-channel decomposition and reconstruction closed loops were applied for sense mode operation.
  • Experimental characterization of temperature effects on zero bias was performed.
  • A practical compensation method was developed and applied.

Main Results:

  • The decoupled design successfully prevented interaction between useful and quadrature signals.
  • The silicon microgyroscope achieved a zero bias stability of 15 (°)/h within the ± 300 deg/s range.
  • Worse-case nonlinearity was measured at 400 ppm.
  • Temperature compensation effectively reduced the maximum bias value by one tenth across -40 °C to 80 °C.

Conclusions:

  • The designed silicon microgyroscope with a decoupled structure demonstrates high performance and stability.
  • The implemented temperature compensation method significantly mitigates bias errors, improving reliability.
  • This SMG is suitable for applications requiring accurate angular rate sensing over a wide temperature range.
