Certain nonlinear partially observable stochastic optimal control problems with explicit control laws equivalent to LEQG/LQG problems
(1997)This paper is concerned with partially observed stochastic optimal control problems when nonlinearities enter the dynamics of the unobservable state and the observations as gradients of potential functions. Explicit ...

Finite-dimensional nonlinear output feedback dynamic games and bounds for sector nonlinearities
(1999)In general, nonlinear output feedback dynamic games are infinite-dimensional. This paper treats a class of minimax games when the nonlinearities enter the dynamics of the unobservable states. An information state approach ...
