Engineering Research Seminar Series 16, 2012: Experiment Design for System Identification

Dr Tan Ai Hui, Associate Professor from Multimedia University

Date: 2012-07-18
Time: 14:00 to 15:00
Venue: Classroom 9-3-03


Good experiment design is key to successful identification test, as it will determine the quality of data collected from an experiment. Some basic considerations in experiment design will be presented. The main classes of perturbation signals and their properties will be discussed. These include fixed spectrum signals, computer-optimized signals and hybrid signals. The factors which should be taken into account when selecting suitable perturbations signals will be explained. Finally, the concepts are illustrated through an application example on a cooling system.
