Title: Vibrating structure piezoelectric hollow cylinder gyroscope
Authors: Singh, A K
Issue Date: Feb-2005
Publisher: CSIR
IPC CodeG01C 19/00
Abstract: This paper presents the development of piezoelectric vibrating structure gyroscope. The vibrating structure used here is made of piezoelectric PZT-5J and cylindrical in shape. It has eight equally spaced positive electrodes on the outer side and one common negative electrode on the inner side. Two of the positive electrodes are used for excitation of the structure and two for detection. The excitation of structure is done at its resonance frequency providing maximum sensitivity. The performance of the developed piezoelectric gyroscope is tested with a microprocessor controlled turntable. Signal conditioning with automatic gain control (AGC) and results, for clockwise and anti-clockwise rotations for different rotation speeds, are discussed in the paper.
