Abstract :
Proposes a methodology for the synthesis of nonlinear finite-dimensional time-varying output feedback controllers for systems of quasi-linear parabolic partial differential equations with time-dependent spatial domains. The method is successfully applied to a typical diffusion reaction process whose spatial domain changes with time and is shown to outperform a controller design method which does not account for the variation of the spatial domain
