This paper deals with the problem of H_{infty} and robust H_{infty} control, via dynamic output feedback, of continuous time Active Fault Tolerant Control Systems with Markovian Parameters (AFTCSMP) subject to both structured and unstructured parameter uncertainties. The above problematic is addressed under a convex programming approach. Indeed, the fundamental tool in the analysis is an LMI (Linear Matrix Inequalities) characterization of dynamical compensators that stochastically (robustly) stabilize the closed loop system and ensure H_{infty} and robust H_{infty} performances. Numerical examples are presented to illustrate the theoretical results.
