Parameter and state variable estimation of nonlinear distributed parameter bioreactors

Boubaker O., Babary J.

Archives of Control Sciences

Vol. 9, no. 3/4

93-110

Due to a lack of on-line reliable sensors, the measurement of biological variables such as biomass concentration and its specific growth rate, is not possible; this fact can be a difficulty, mainly when considering state feedback control problems. The aim of this paper consists of designing an estimator of biological variables and parameters in the case of a nonlinear distributed parameter bioreactor. By applying an orthogonal collocation method, the distributed parameter model is transformed into a lumped parameter model. Then, a joint estimator of time-varying parameters and state variables is designed by using asymptotic stability properties. Simulation runs show the feasibility and the robustness of the estimator designed for this nonlinear process.
