A finite element model is proposed to calculate the mechanical state of a moored aerostat system. The difficulty in matching the loads of the tethers is overcome by releasing the tether constraints and applying the load step by step. The causes of non-convergence during computation is investigated and solved by modifying the criterion appropriately.

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.
