| 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. |
