Controller design of systems with multiplicative noise. (English) Zbl 0569.93070

Continuous stochastic systems acted upon by scalar multiplicative and vector additive noises are considered. First examined is the problem of finite-horizon control of such a stochastic system with time-varying parameters under the additional constraint of incomplete state information. The necessary conditions for optimality of the solution are expressed in terms of nonlinear matrix differential equations. Next, taken up is the infinite-horizon case with constant parameters, and the result is given in terms of nonlinear algebraic equations to be solved.
