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 Y₁; parameter acquisition means for acquiring A, ω₀ and t₀ when the digital excitation signal is represented by an expression (1) of Y₁=A*sin(ω₀*(t-t₀)); and resolver sensor signal creation means for creating digital resolver sensor signals R₁ and R₂ represented by expressions (2) R₁=A*sin(ω₀*(t-t₀-Δt₁))*K*sin(X*θ_m and (3) R₂=A*sin(ω₀*(t-t₀-Δt₁))*K*cos(X*θ_m on the basis of an angle signal θ_m input from simulation rotary equipment.;COPYRIGHT: (C)2015,JPO&INPIT
