Robust Optimal Control of Distributed Parameter Systems

Back
Abstract:
In this research, computationally efficient methods are proposed for the optimal control of distributed parameter systems (DPS), in which robustness is ensured regardless of whether (i) the DPS is approximated by ODEs before the design of a finite-dimensional controller, or (ii) an infinite-dimensional controller designed directly from the DPS is approximated by a finite-dimensional controller. The talk will provide an overview of deterministic and stochastic robustness analysis for linear DPS and finite-time nonlinear DPS based on H-infinity operators, polynomial chaos, and power series expansions. A suite of control techniques will be demonstrated by application to boundary and spatial field control problems described by reaction-convection-diffusion equations.
