FLORES-ESTRELLA, R.A.; ESTRADA-BALTAZAR, A.  and  FEMAT, R.. A mathematical model and dynamic analysis of anaerobic digestion of soluble organic fraction of municipal solid waste towards control design. Rev. Mex. Ing. Quím [online]. 2016, vol.15, n.1, pp.243-258. ISSN 1665-2738.

A dynamical model for anaerobic digestion (AD) is proposed for the soluble organic fraction of solid waste. The model is proposed with the purpose of showing the feedback control of the process. The control scheme concerns the output regulation of the organic matter effluent by achieving desired operation conditions, which are featured by the operational stability. The operating conditions for the digester correspond to organic matter degradation and are named normal operation conditions, which are computed from nontrivial equilibrium. Both the acidogenic and the methanogenic stages are considered in dynamical model; including substrate and product inhibition. A PI feedback control is designed in order to illustrate the control problem is solvable.
