Optimal Averaging Level Control for Multi-Tank Systems

Abstract In this paper earlier results on optimal averaging level control (McDonald et al, 1986) are extended to cover the case where two or more tanks are connected in series. It is shown that the optimal averaging level control approaches can be derived for a multiple tank system if the total volumetric capacity of the system is taken into account. Intermediate flows between tanks are arbitrary, provided they satisfy the level constraints. The optimal solutions that consider tanks together produce beuer flow filtering than the optimal averaging level control approaches where each Lank is treated individually.
