Comparison between ARMA and Sub-Space Identification Method for Modelling of Air Separation Unit
نویسندگان
چکیده
–In the present work two popular methods for modelling a system are compared using modelling of Air Separation Unit (ASU). To Model any MIMO system in general both ARMA and Subspace Identification methods can be used, and the optimum results can be achieved only after thorough investigation in the actual process of the system and the methodology by which the modelling can be done so as to suit our requirements. A higher order system can be modelled improving its overall stability, as well as a system with lower order can be modelled with less complexity. Keywords––MIMO, ASU, System identification, ARMA, N4SID.

Simulation of a membrane air separation unit using industrial process simulators
Nowadays, membrane processes are widely used for high purity Nitrogen production. Separation of air by membranes is a flexible process in which the investment and operational costs are lower than for example adsorption or cryogenic processes. Such processes are based on relative permeability of air components which are transported by the pressure difference between two sides of the membrane. M...

متن کاملIdentification of an Autonomous Underwater Vehicle Dynamic Using Extended Kalman Filter with ARMA Noise Model
In the procedure of designing an underwater vehicle or robot, its maneuverability and controllability must be simulated and tested, before the product is finalized for manufacturing. Since the hydrodynamic forces and moments highly affect the dynamic and maneuverability of the system, they must be estimated with a reasonable accuracy. In this study, hydrodynamic coefficients of an autonomous un...
