Abstract :
The start-up and the shutdown of tubular fixed-bed reactors can be improved by an explicit trajectory design and active control. By using the inflow concentration as a control the outflow concentration can be changed in arbitrary finite time. Explicit series expansions of the control inputs are calculated using the distributed parameter system model. It is shown that these promising techniques are not restricted to the single-input case, but can easily be extended to certain multivariable models. The control laws derived are new in the scalar case
