SENSOR ERROR CORRECTION DEVICE, SENSOR ERROR CORRECTION METHOD, AND PROGRAM FOR SENSOR ERROR CORRECTION

摘要

PROBLEM TO BE SOLVED: To make a system low-cost by reducing the processing load and resource consumption of a computer which makes sensor error correction as compared with the prior art.;SOLUTION: The sensor error correction device comprises: a rotation angle detection part which detects a rotation angle θ of a motor based upon an output signal from a resolver which detects the rotation angle; a rotation speed detection part which detects a rotation speed V based upon the rotation angle θ; a sampling part which samples the rotation speed V and generates and outputs a rotation speed sample value; a rotation speed averaging part which averages rotation speed sample values Vs and generates and outputs a rotation speed average value V'; and an integration part which integrates rotation speed average values V' and generates and outputs a rotation angle θ'.;COPYRIGHT: (C)2012,JPO&INPIT
