Experimental identification of the mechatronic system

Abstract

The experimental identification of mechatronics system involves the exploration and implementation of different identification methods and approaches that can be used to approximate the dynamic behaviour of a real-world system or a simulation model. This involves the development of simulation model of DC motor driven lead screw and application of different approximation methods on it. Then the experience gained is used to approximate the real system. The physical system consists of a test rig equipped with a linear actuator that drives a platform designed to lift a load. The behaviour of this system is recorded and processed in different approaches to estimate the mathematical representation, which includes the traditional “One-shot” identification and the “Recursive estimation” using the MATLAB Simulink environment. It also encloses the implementation of State observer and Kalman filter based observer at simulation level.
