In this work, a global constrained adaptive output feedback is presented for a class of plug-flow tubular reactors models described by non-linear partial differential equations. The output of the system is the measured temperature in a fixed zone of the reactor. It is then used to regulate the temperature throughout the reactor to a ball with radius λ (arbitrarily small) centred at the fixed temperature profile.
