| Abstract: | Multimodel analysis and controller design for nonlinear processes via gap metric is discussed. It is shown that the loop-shaping H∞ 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 can have similar performance, and the global performance of the system can be predicted. |
