Abstract

This paper considers the identification of a multivariable nonlinear and time-varying mist reactor system which presents an important system in the industry for applications in cell culture. A systematic approach is formulated for characterizing the linear dynamics, nonlinear distortion, disturbing noise and time variation. The best time-invariant approximation is introduced as part of the methodology in the proposed approach. By incorporating significant nonlinear terms into the model, the main source of disturbance can be determined with greater confidence. The power at the different harmonics is further capitalized upon in deriving an indicator for the relative variance of the time-varying delay.
