摘　　要：In this study,the fixed-time stabilization problem of stochastic high-order nonlinear systems with output constraint and high-order and low-order nonlinearities is addressed.A new coordinate transformation is employed to directly convert output-constrained stochastic systems into an equivalent unconstrained form.By fully extracting the characteristics of system nonlinearities and using the stochastic fixed-time stability theorem,a new design and analysis method is constructed to guarantee that the trivial solution of the closed-loop system is stochastically fixed-time stable while fulfilling the output constraint.
