Abstract : "This paper addresses the genetic algorithm (GA) optimization and the linear quadratic (LQ) structure
based predictive functional control (PFC) for batch processes under non-repetitive unknown disturbances and partial
actuator faults. First, by adopting the extended non-minimal state space (ENMSS) model in which the state variables
and the tracking error are united, the new state vector with more degrees is provided for the controller design. In
order to enhance the ensemble control performance under the PFC structure, GA is adopted for the optimization
of the weighting matrix in the controller. The case study on the injection velocity control in an injection molding
machine demonstrates the effectiveness of the proposed PFC scheme against various disadvantages."
