Backstepping controller design for nonlinear stochastic systems under a risk-sensitive cost criterion. (English) Zbl 0924.93046
This paper develops a methodology for recursive construction of optimal and near-optimal controllers for strict-feedback stochastic nonlinear systems, given by stochastic differential equations, under a risk-sensitive cost function criterion. The authors investigated cost-level satisfaction problems and obtained the design procedure, using the integrator backstepping procedure. They also extended these results to nonlinear systems with zero dynamics. The theoretical results are applied to a second-order system as a numerical example.
