ABSTRACT
The measured quantity may be a constant parameter (e.g., moment of inertia of a link of a robotic arm), an average property of a batch of items (e.g., average internal diameter and its variance of a batch of ball bearings), varying parameter (e.g., resistance of a strain gauge as the temperature changes), or a process variable (e.g., velocity of a vehicle). The sensor measurement may not provide the true value of the required parameter or variable, for two main reasons:
1.What is measured may not be the required quantity, and will have to be computed from the measured value (or values) using a suitable model.
