The sensors output datum are collected and optimized in the embedded system by adopting the low cost piezoelectric gyroscopes and accelerometers are adopted and the high precision A/D converter chip and the high performance DSP are used.

Based on the noise feature of the piezoelectric gyroscope and how to select method of the structure element,structure elements of the half-circle,triangle and the cosine were used to make up a paralleling complex morphology filter.

Random drifting is an important index of piezoelectric gyroscope.

The piezoelectric gyro is a new solid-state gyro for inertia rate sensor,which is provided with many superior characteristics for modern weapon servo system,such as small size,light weight,wide dynamic range,little nonlinear error and tolerance for hard environment,etc.

This paper presents a method of quick zero-calibration for gyro according to the characteristic of piezoelectric gyro.

A low-cost miniature signal-correcting module is developed for three-axis piezoelectric gyro unit with the use of new MCU and reasonable signal conditioning circuit design.

The influence of the gyroscopic moment produced by the rolling rotor on the dynamic characteristics of the principal axis system of certain dish centrifuge is analyzed theoretically.

This method utilizes a gyroscopic moment which is produced from the forced precession of a high-speed rotor whose axis is changed by another moment,to upright the robot s body.

Based on flexible rotor system, using the model of unsteady nonlinear oil film forces acting on journal bearing, the model of nonlinear rotor bear system of 8DOFs involving the effect of gyroscopic moment is formulated in this paper.
