Location of work: Chemical and Materials
Engineering Building (Room 270)- University of Alberta
Research Interests:
Continuous-time Identification
The importance of continuous-time approach in identification in the
recent scene dominated by discrete-time approach has been recognized
increasingly. The ease of understanding and physical interpretation
of continuous time models has greater appeal than its discrete-time
counterpart. This has led to an increasing interest in the field of
continuous-time identification. Development of continuous-time identification
methods for single input single output and multiple input multiple output
continuous-time models is the objective of this project.
Continuous-time Model Validation
Model validation through the detection of model parameter changes is an effective way of monitoring a process. The asymptotic local approach is popularly used for model validation. The objective of this project is to develop method for model validation through detection and isolation of changes in the parameters and the delay of continuous-time models.
