In this paper, the inverse optimal gain assignment problem for a class of stochastic nonlinear systems with Markovian jump parameters is investigated. Firstly, a sufficient condition to solve this problem for Markovian jump nonlinear systems with bounded indefinite Wiener noises is given. Then, the control strategies of global asymptotic stability and inverse optimal stabilization in probability are presented for a class of strict feedback nonlinear systems. To avoid dealing with the ＂interconnected＂ term caused by Markovian jump, the Lyapunov function and the controller are designed to be independent of the regime. Finally, simulation verifies the effectiveness of the control algorithm.
