Unisothermal control of a cascade of continuous stirred tank reactors was analyzed. The control strategy is based on keeping the same degree of the thermal stability for all reactors in the cascade. The cooling driving force (the stationary temperature difference between the reaction mixture and the coolant) was used as the measure of the thermal regime stability. The structure of possible steady states was established, the thermal stability and technological properties of steady states were discussed. The most advantageous set of stationary states is recommended and the possibility of practical application of the suggested control strategy was discussed.
