a Measurement and control scheme of the HDRG under VM. The virtual switch (VS) is used to change the working state of the HDRG. b Test results of the bias when the HDRG is working under α = 0°. c Test results of the bias when the HDRG is working under α = 90°. d Final bias of the HDRG according to the two working states (α = 0° and α = 90°) under VM. There is no final bias in the first working state when α = 0° because of missing data from the previous working state
