| Robust disturbance attenuation of fluid dynamic systems with norm-bounded uncertainties (2001) | |
Abstract | |
| In this paper, we consider the problem of robust control of fluid dynamic systems in an H∞ sense. The system under study is nonlinear in state and linear in inputs with parameter uncertainties in all entries. The controller is designed, via Hamilton-Jacobi equation and Riccati equation approaches, such that the resulting closed-loop systems is robust stable and has a robust H∞ performance. In particular, it is shown that the robust H∞ control problem is solvable for a nonlinear system (governed by Navier-Stokes equation) in the neighbourhood of the origin if a robust H∞ control problem is solvable for a corresponding linearized system. | |
