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.

For the aim of saving energy and optimizing control of chilled systems, the performance of VWV systems and characteristics of control systems were analyzed based on the simulation. According to the characteristic of the monitored parameters and controlled variables in VWV systems, three online optimal control strategies were proposed and validated:(1) Optimal strategy for on/off control of chillers according to the ratio of secondary flow rate to primary flow rate.(2) Optimal strategy for the control of secondary pump according to value positions of auto-controlled AHU vales. And (3) Optimal strategy for supply chilled water temperature control of chillers according to valve positions of auto-controlled AHU valves and working status of secondary pump.

Applying LMI technique, quadratic stability theory, and H〓 control theory, three methods of robust stability analysis and robust controller design for uncertain fuzzy systems are proposed respectively. Among them, LMI based technique can analyze the uncertainties raised in the premises and in the consequent of fuzzy systems. The resulting stabilizing state feedback controllers have maximum stability margins for both kinds of uncertainties. Quadratic stability theory based approach can apply LMI technique and other methods to design fuzzy controllers. H〓 control theory based design can get H〓 controller with constant disturbance attenuation for each local subsystem. Using the given stability criterion of generalized systems, the robust stability of fuzzy systems can be checked.
