adaptive model predictive control of an anaerobic digestion reactor

In this work, an adaptive model predictive controller has been applied for controlling an anaerobic digestion reactor# an arma model has been used to estimate the predicted values of the system output over the prediction horizon# as the process is highly nonlinear, model parameters are updated at each sample time to capture system nonlinearities# the controller has been designed based on the input-output model which does not require the system state measurements for control implementation# for the simulation purpose, the adm1 model which includes the four main involved mechanisms in anaerobic digestion has been utilized# in simulation study the controller performance has been tested for setpoint tracking, load rejection and model mismatch# the results indicate that desired trajectory has been tracked well in the presence of different types of external loads and model uncertainties#
