Multivariable adaptive predictive control of an aerated lagoon for a wastewater treatment process
Latin Abstract :
The application of an adaptive multivariable predictive model-based control scheme for the control of
biotechnological processes is reported. Control design consists of regulating the residual concentrations of
two main variables of a multistage wastewater treatment process. Unavailability of measurements leads
to the development of an identification technique derived to estimate simultaneously unavailable state
variables and time-varying parameters of a nonlinear process. Convergence of the estimation scheme is
demonstrated via a theorem and its proof using Lyapunovʹs method. The estimated variables are used in
the explicit design of the control algorithm. Good simulation results have been obtained in regulation,
tracking, disturbance rejection and transient behaviour, showing the efficiency of this adaptive control
strategy.
