AbstractIn this work methods for generating sets of excitation signals for system identification are discussed and evaluated. This study is focused on applications in the process industries, particularly in oil refining.The operational constraints of the oil refining industry are becoming increasingly severe due to increased energy demand, quality of products, oil price variations, market competition and other economic, environmental and energy efficiency factors. In this scenario the use of model predictive control techniques is increasing, thus the demand for plant identification as well.
