the different model order, respectively. The smaller Op
Ob denote the better modeling accuracy. In the present calibrations,
the Oub/Op
, Oub
could achieve a minimum of 0.223
and 0.232, respectively. Fig. 5d, Fig. 5e and Fig. 5f display the
distribution of ep
, eub and eb under the different model order n
and data span. It reveals that a Runge phenomenon appears
in the PCM over the whole measurement range of the linear
potentiometer. As a result, the PCM produces a remarkable periodical
calibration error over the whole measurement range,
as shown in Fig. 5d. Fig. 5c, Fig. 5d and Fig. 5f reveal that the
UBCM and BCM models could greatly reduce the measurement
error, and that they are smoother than that of the PCM.
