Considering nonlinear behaviors and environmental disturbance of the boiler pressure controlsystem, a linear interpolation fuzzy controller is developed. First, according to the conventional discrete fuzzy control principle, a discrete fuzzy controller for the system is designed and a 2-D fuzzy control lookup table is deduced. Then, to overcome the conventional fuzzy controller's disadvantage of lower precision caused by discretization, a bilinear interpolation 2-D table lookup method is used to replace the exact lookup method, with which continuous output can be obtained from the discrete control table. Finally, based on the existed computer controlsystem and boiler system hardware configuration, hard-in-loop real-time simulation system is established in Matlab/RTWT. Lots of experiments are carried out. And the results prove that better control performance can be achieved with the proposed control scheme.

Fano resonances in plasmonic nanostructures have asymmetric line shape and sharp resonance, and they are very attractive for biosensing applications. The implementations of biosensing rely on plasmon line shape engineering. In this work, we report that when the symmetry of a hexamer is lowered to D 2h point group, two B 3u and two B 2u dark subradiant modes are excited, and there are four kinds of Fano resonances. According to plasmon hybridization theory, the B 3u and two B 2u modes interact with plasmons of the central partical for heptamers with D 2h symmetry. We demonstrate that besides the influence on the resonance behavior, or the appearance of an additional Fano resonance for a certain polarization, there are several hybridized dark subradiant modes for both polarizations, and up to eight kinds of Fano resonances appear in the spectra. Plasmonic clusters with D 2h symmetry are very suitable for plasmon line shaping, and they would useful for multi-wavelength sensing applications. This work also reveals that cluster symmetry engineering is a good method to tune spectral features and to form multiple Fano resonances, and one can get similar results for plasmonic clusters with other symmetries.
