Resumen
Objective: To design, tune, and comparatively evaluate four model-free sliding mode control (MF-SMC) strategies to robustly stabilize biohydrogen production in a simulated continuous stirred-tank reactor (CSTR).
Design/methodology/approach: Robust control and optimization techniques are used in this study.
Results: MF-SCM strategies can handle nonlinearities and disturbances.
Limitations on study/implications: The study was conducted in a simulated environment; findings require validation in a physical laboratory-scale bioreactor.
Findings/conclusions: The MF-SMC strategy, tuned via genetic algorithms, is a viable and robust tool for controlling biohydrogen production, effectively handling nonlinearities and disturbances.Sliding mode control, biohydrogen production, CSTR, genetic algorithm, robust control.
