SIMULATION RESOLVER AND CREATION METHOD OF RESOLVER SENSOR SIGNAL

摘要

PROBLEM TO BE SOLVED: To provide a simulation resolver capable of creating an accurate resolver sensor signal, and a creation method of a resolver sensor signal.SOLUTION: The simulation resolver includes: input means for inputting an analog excitation signal; digital conversion means for converting the analog excitation signal into a digital excitation signal Y; parameter acquisition means for acquiring A,ωand twhen the digital excitation signal is represented by an expression (1) of Y=A*sin(ω*(t-t)); and resolver sensor signal creation means for creating digital resolver sensor signals Rand Rrepresented by expressions (2) R=A*sin(ω*(t-t-Δt))*K*sin(X*θand (3) R=A*sin(ω*(t-t-Δt))*K*cos(X*θon the basis of an angle signalθinput from simulation rotary equipment.
