Investigation of Pulse Torquing Systems

In this paper, a pulse torquing loop of a force integrating type sensor is investigated with the aim of increasing the measurement accuracy by choosing the proper design parameters, viz., sampling frequency and deadband. From the results, it is advisable to employ as high a sampling frequency as possible, while further improvements in performance can be obtained by operating the system in ternary mode with a deadband value, approximately equal to half the quantized output.
