“…Legros et al ( 1995) and Marmo et al ( 1995) divided the riser into 2 parts with the lower dense region being considered as a perfectly mixed turbulent bed rather than in plug flow. The solids are considered either well-mixed (Arena et al, 1995), in plug flow (Muir et al, 1997;Saraiva et al, 1993), or in bubbling bed mode (Saraiva et al, 1993;Zhang et al, 1991).…”

“…Accurate reactor modeling requires hydrodynamics, heat and mass transfer, as well as reaction kinetics, in order to predict reactor performance. Several CFB modeling approaches lead to models with different degrees of sophistication (Grace and Lim, 1997;Hyppanen et al, 1991;Gidaspow, 1994). While the cyclone, downer or annulus are commonly treated as well mixed or plug flow systems, the riser modeling varies a lot: from homogeneous to heterogeneous modeling, from single-region to multiple-region modeling and from OD to 3D modeling, or a combination of these approaches.…”

“…Suppose the state space is partitioned into a number of regions as , which can be approximated by a degenerate ellipsoid [30], , with and . Then we have the following inequality for this ellipsoid region: (6) which can be applied in the -procedure to the LMIs in (5) as in [13], [30], and [31]. Note that .…”

“…With the development of modern control theory, model-based control strategies such as generalized predictive control (GPC) are available for the optimization and control of FBC process system [3], [6]. The GPC approach has been developed on the linear FBC model; thus, its transient control performance may deteriorate, even lead to instability due to large load changes of the FBC plant.…”
