Multimodel analysis and controller design for nonlinear processes via gap metric is discussed. It is shown that the loop-shapin, H-infinity approach can integrate the procedure of selecting operating points and the local controller design. The local controllers can guarantee not only stability but also performance specified by the pre- and/or post-compensators. Thus, at each operating points, local controllers cart have similar performance, and the global performance of the system can be predicted. (C) 2004 Elsevier Ltd. All rights reserved.
