IDENTIFICATION OF PENDULUM OSCILLATION PARAMETERS USING MEMS ACCELEROMETER

Abstract

The article deals with analysis of problematic focused on identification of pendulum oscillation parameters. Theory is based on mathematical description of physical pendulum with real damping and kinematics theory. The article describes experimental laboratory model of physical pendulum with precise construction. Simultaneously it describes wireless sensor system with dual axis MEMS accelerometer, which is used for components accelerations measurement of free oscillating pendulum arm. The article presents methodology for solution which is based on expression of boundary conditions and follows prediction of actual angle displacement in next period of oscillation. Experimental measurement and its subsequent evaluation determine properties and usefulness of principles of measurement and evaluation in purposes of control and visualization. Final evaluation offers suggestions for future improvement of described method.
