dc.description.abstractThis thesis is mainly concerned with the studies of the robust stabilization of stochastic differential equations in Hilbert spaces. Based on the stability radius approach, we investigate the robust stabilization of infinite dimensional systems subjected to stochastic structured bounded and unbounded perturbations with bounded and unbounded input operator. The maximization of the stability radius is studied by state feedback and by dynamic output feedback. Conditions for the existence of suboptimal controllers are introduced in terms of Riccati equations satisfying some operator inequalities. Moreover, lower bounds for the supremal achievable stability radius are obtained.
