Fuzzy Optimal Guaranteed Cost Control of a Single Specie Bio-Economic Singular Systems in Algae Environment

In this article, the problem of optimal guaranteed cost control for a single specie bio-economic singular system in an algal environment is investigated using fuzzy methods. Based on the aquaculture of whitebait in algae environment, a class of non-linear bio-economic model is established. In addition, owing to the practical problem of a finite production cycle and the need to control biomass within a certain range, a cost-guaranteed controller based on a fuzzy model was developed to ensure that the biomass concentration reaches a certain range in a limited time and at a minimum cost. Finally, the feasibility of the developed controller is demonstrated through a practical example.
