Abstract :
We study the design of dynamic nonlinear robust output feedback for the stabilization of a class of continuously stirred bioreactors. In this paper, we propose a new robust approach in which all the uncertainties are considered as bounded disturbances. This method allows one to design dynamically bounds on unmeasured variables, that are conditioned to measurements and to given bounds on initial conditions
