Output-feedback stabilization for stochastic nonlinear systems whose linearizations are not stabilizable. (English) Zbl 1193.93146

Summary: This brief paper investigates the problem of output-feedback stabilization for a class of high-order stochastic nonlinear systems which are neither necessarily feedback linearizable nor affine in the control input. Based on the ideas of the homogeneous systems theory and the adding of a power integrator technique, an output-feedback controller is constructed to ensure that the equilibrium at the origin of the closed-loop system is globally asymptotically stable in probability. The efficiency of the output-feedback controller is demonstrated by a simulation example.
