Query: Predictive Control Based on Reduced Order Model for temperature
  homogeneity in a resin transfer molding tool for thermoset materials   Resin Transfer Molding (RTM), which has attracted much attention in the last
years for lightweight manufacturing, represents an important challenge in terms
of control technology. During the process, a resin fills the cavity where a
reinforcement fabric has previously been layered. This resin undergoes a
chemical reaction which is thermically activated. Therefore, assuring a proper
reaction requires a precise control of temperature in the entire mold cavity.
Three factors make this control problem especially hard: the coupling among the
large number of actuators and sensors, the variability of the test conditions
and the power limitations of the electric actuators which do not offer cooling
capability. The present work describes an optimized Model Predictive Control
(MPC) architecture capable of handling these difficulties and also achieving
the tight control requirements needed in the application. The thermal
distribution inside the mold cavity is included into the controller by a
simplified Reduced Order Model (ROM). This representation is obtained by data
from an experimentally validated Finite Element Model (FEM), using
AutoRegressive model with eXogenous terms (ARX) identification. In order to
maintain the simplicity of this linear representation, the time-varying model
parameters are estimated by using a perturbation observer. Additionally, the
performance of the basic algorithm is improved: firstly, an augmented observer
to estimate the temperature distribution of an extended spatial resolution; and
secondly, a symmetry condition in the calculation of the control commands. The
developed architectures have successfully been implemented in a RTM tool with
the fulfillment of the control requirements.
