Abstract
Presented in this paper is a time optimal control of chemical reactor which starts up in the shortest time the reactor from an arbitrary initial state to a steady state of desired concentration and temperature. The reactor considered here consists of a continuously and perfectly stirred tank and a piston flow type tube. Theoretical analyses and experiments are both carried out, applying _??_'s Maximum Principle. Optimal solution is obtained for the non-linear mathematical models which express the dynamics of reaction. Digital differential analyzer is used for calculating the optimal switching lines and trajectories. As its result, it is proved that when this optima control is experimentally compared with conventional P. I. D. -mode control system, the former has improved the control efficiency to a larcre eytent.
