Abstract :
Discontinuous control methods are developed for minimum phase semilinear infinite-dimensional systems driven in a Hilbert space. Control algorithms presented ensure asymptotic stability, global or local accordingly as state feedback or output feedback is available. Useful robustness properties against external disturbances with the a priori known norm bounds are provided for the closed-loop system. The theory is applied to stabilization of chemical processes around prespecified steady-state temperature and concentration profiles corresponding to a desired coolant temperature
