Abstract

We present prescribed-time output-feedback-stabilizing designs for stochastic nonlinear strict-feedback systems. We first propose a new nonscaling output-feedback control scheme to solve the prescribed-time mean-square stabilization problem for stochastic nonlinear systems without sensor uncertainty. In this case, compared with the existing results on stochastic nonlinear prescribed-time stabilization, an appealing feature in our design is that the order of the scaling function in the controller is dramatically reduced, which yields a simpler controller and with the control effort reduced. We then consider prescribed-time output-feedback control for stochastic nonlinear systems with sensor uncertainty. In this…
