control of a continuous biodiesel production reactor

Biodiesel is a sustainable fuel mainly produced by transesterification of oils# the control of the biodiesel production reactor is a challenging problem due to the nonlinearity of the process# in this work, an adaptive multivariable generalized model predictive control(gpc) has been applied to a biodiesel reactor to control the mass fraction of the produced ester and the reactor temperature# based on open loop responses, a linear transfer function between system inputs and outputs has been obtained# to capture the system nonlinear dynamics, the model parameters updated at each sampling time# the results indicate that the controller has a good performance in setpoint tracking, load rejection and in case of model mismatch#
