Boundary Control of an Industrial Tubular Photobioreactor Using Sliding Mode Control

Abstract In this paper, the pH boundary control problem of a tubular photobioreactor is treated. The method of characteristics is used to transform the hyperbolic system of equations into a set of first order ordinary differential equations without approximation. The proposed approach is geometric in nature. The method is shown to be effective in controlling pH concentration of a tubular photobioreactor through simulations under real data disturbances.
