WebIn general, unless you are interested in experimenting with numerical methods, I recommend using an existing PDE solver instead of trying to write one yourself. This advice is particularly true for numerically-challenging problems, like yours appears to be. WebThe system of coupled equations includes a parabolic PDE with algebraic boundary conditions (representing the tubular reactor), while the ODE refers to the CSTR model dynamics. The discrete Luenberger observer is designed to account for the system output and its stability is based on the design in the continuous-time setting.
