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.]]></p></abstract>

El modelo es propuesto con el propósito de mostrar una ley de control del proceso. El esquema de control consiste en la regulación de la materia orgánica efluente como señal de salida mediante el mantenimiento de condiciones deseadas, las cuales incluyen la estabilidad operacional. Las condiciones de operación para el digestor corresponden a la degradación de la materia orgánica y son llamadas condiciones normales de operación, las cuales son calculadas de un equilibrio no trivial. El modelo dinámico considera las etapas acidogénica y metanogénica; substrato y la inhibición por producto. Un control PI retroalimentado es diseñado para ilustrar que el problema de control es resoluble.]]></p></abstract>
