Vibrerende rotasjonssensor med anvendelse av lineariserte b÷yningsmÕlinger

摘要

The method involves generating one or more linearising weighting functions Gil(Pm) for which the output signal is the linear measure of the parameter (Pm) to the specified accuracy of representation. The input signal Gil(Pm)Hi(Pm) are fed into the sensor. Gi(Pm)Hi(Pm)Eoi(t) is summed over `i' at the output port based on input signals Gi(Pm)Eei(t) where Gi(Pm) is a weighting function associated with the ith input port, Eei(t) is an excitation signal associated with the ith input port, Eoi(t) is the transformation of the excitation signal Eei(t) resulting from Eei(t) traversing the path from the input port `i' to the output port. Eei(t) and Eoi(t) are independent of the parameter (Pm), the product function Gi(Pm)Hi(Pm) is represented by a power series of order Nim in (Pm). The value of Nim depends on a specified accuracy of representation. The component of the input signal is used as a linear measure of each of one or more parameter (Pm).
