<P>PROBLEM TO BE SOLVED: To provide a system for estimating an attitude or a velocity state of a rotary object, without including an integration operation in data processing, or by including minimally an integration operation processing step. <P>SOLUTION: A tilt angle estimation system is a system having one rotation center point, and estimates a tilt angle of an object rotating and simultaneously tilting in one plane centering on the rotation center point. The tilt angle estimation system comprises: at least two acceleration sensors mounted on the object; and an arithmetic processing unit for receiving each output from at least two acceleration sensors and calculating the tilt angle of the object on the basis of the output. 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. <P>COPYRIGHT: (C)2013,JPO&INPIT |
