Optimal calibration plan for inertial measurement unit based on microelectromechanical system

Abstract

Abstract This paper is about the composition of scientifically substantiated calibration plan from the specific requirements for inertial measurement unit on microelectromechanical sensors. It is proposed to decompose the common problem into three tasks – converting implicit requirements to the explicit requirements with error components, determining of requirements by indirect parameters and finding direct parameter values, time limited calibration that have limits for full time. All these tasks may be presented as multi-criteria optimizations and be solved by numerical methods with some semi-analytical substitutions. Suggested methods are useful for composing an optimal calibration plan in conditions of ambiguous requirements, to estimate reaching accuracy, test volume and total calibration time. This approach offers the researcher a new look at the problem of balance between calibration accuracy and optimal use of resources.
