The H-2, H-infinity and mixed H-2/H-infinity dynamic output feedback control of Markov jump linear systems in a partial observation context is studied through an iterative approach. By partial information, we mean that neither the state variable x(k) nor the Markov chain theta(k) are available to the controller. Instead, we assume that the controller relies only on an output y(k) and a measured variable theta<\^{}>(k) coming from a detector that provides the only information of the Markov chain theta(k). To solve the problem, we resort to an iterative method that starts with a state-feedback controller and solves at each iteration a linear matrix inequality optimization problem. It is shown that this iterative algorithm yields to a nonincreasing sequence of upper bound costs so that it converges to a minimum value. The effectiveness of the iterative procedure is illustrated by means of two examples in which the conservatism between the upper bounds and actual costs is significantly reduced. (AU)
