摘要
This paper deals with the control of fixed bed bioreactors. The dynamics of these processes are described by a nonlinear distributed parameter model. In a first step, the partial differential equations of the model are reduced to ordinary differential equations by using an orthogonal collocation method. A nonlinear adpative controller is then designed, which is based on the nonlinear discretized model. Its performance is illustrated by simulation results on a fixed bed anaerobic waste water treatment process.
