Abstract :
The problem of dynamic output-feedback control is solved for linear retarded discrete-time state multiplicative stochastic systems. The stochastic white noise sequences multiply both the delayed and the non-delayed states and the input signal of the systems. The problem is solved, for the stationary case, for both nominal and uncertain polytopic systems, via the input-output approach by which the system is replaced by a nonretarded system with deterministic norm-bounded uncertainties. In both cases, a cost function is defined which is the expected value of the standard H∞ performance index with respect to the uncertain parameters.
