Reliable parameter estimation for dynamic systems with big data

Project Member(s): Su, S.

Funding or Partner Organisation: Commonwealth Scientific and Industrial Research Organisation (Commonwealth Scientific & Industrial Research Organisation)

Start year: 2015

Summary: This project will investigate the optimal design of suitable input signals to stimulate big dynamic system so that the information about the dynamic system can be extracted from the experiments. For the identification of a static model of an inertial sensor, a well selected/designed set of experimental observations with desired properties, in terms of Experimental Design (DoE), can significantly improve the accuracy of system modelling and parameter estimation. Classical static system can be formulated as a static linear parameter identification problem, for which DoE theory has been well established. However, the models associated with the big dynamic system are often nonlinear. This makes the linear approaches, which are effective and theoretically rigorous in traditional research, invalid for big system. This Project will focus on new machine learning based approaches to solve the above problem. New experimental design methods will be proposed to improve the accuracy of parameter estimation. Two performance indices of optimal experimental design, D-optimality and G-optimality, are going to be investigated based on the analysis of the information matrix.
