TILT ANGLE ESTIMATION SYSTEM, RELATIVE ANGLE ESTIMATION SYSTEM, AND ANGULAR VELOCITY ESTIMATION SYSTEM

摘要

PPROBLEM TO BE SOLVED: To provide a system capable of estimating the attitude or the velocity state of a rotary object, without including integration operation in data processing, or by including minimally an integration operation processing step. PSOLUTION: This tilt angle estimation system, which is a system having one rotation center point, for estimating a tilt angle of an object rotating and simultaneously tilting on one plane around the rotation center point, includes at least two acceleration sensors mounted on the object, and an operation processing unit for receiving each output from at least two acceleration sensors and calculating the tilt angle of the object based on the output, and has characteristics wherein at least two acceleration sensors are aligned on one straight line and a line connecting at least two acceleration sensors passes the rotation center point.
