This project is addressed to a systematic study of the model and structural analysis, optimal control and feedback control for several typical deterministic/stochastic distributed parameter systems with significant physical background, and their numerical solutions. The main research topics include: 1) Stability and controllability for some coupled PDEs and some PDEs of higher order, and the numerical approach for these problems; 2) Controllability and stabilization of some quasilinear PDEs, and the nonhomogeneous boundary problem, boundary controllability and continuous dependence of the input-output map for nonlinear dispersive wave equations; 3) Controllability of stochastic PDEs; and 4) Optimal control problem and its numerical method for the general stochastic controlled PDEs with controls appeared in the difussion term.
