In this project, we have tackled the robust fault detection and diagnosis problem for affine nonlinear sampled-data systems based on nonlinear H∞ filtering theory,and focused on the design of robust fault dtetction filter. The main contribution of this project is that we (1)present design methods of robust fault estimator for nonlinear discrete-time systems based on least square estimation and linear matrix inequality;(2)improve the bounded real lemma of systems with finite discrete jumps;(3)develop the robust fault detection filters for affine nonlinear sampled-data systems with parameter uncertainties based on the improved bounded real lemma.

The coupling reaction of aryl iodides, bromides and chlorides with differentolefins catalyzed by catalyst 2 and 4 was studied. It was found that compounds 2 and 4 anchored on active carbon are efficient catalyst for the Heck reaction in the case of aryl bromides and aryl chlorides as substrates (Scheme 3). It is notable that catalyst 4 has higher efficiency for aryl chlorides.___^H Cat.2 or 4, Base HXSolution, 100C or 140

Different from many other researches the Henkel-Esterification process was studied here which starts from 1,8-naphthalenedicarboanhydride. In the Henkel reaction of 1,8-naphthalenedicarboanhydride to 2,6-naphthalenedicarboxylic acid (abbreviated as 2,6-NDA) non-cadmium catalytic system was used. In atmosphere of carbon dioxide 1,8-naphthalenedicarboanhydride can be effectively converted to 2,6-NDA in the temperature range of 300~340℃ with zinc carbonate as catalyst and the yield of 2,6-NDA can reach more over 62%.
