Latent Variable MPC and its Consistency in Temperature Control of Batch Processes
نویسنده
چکیده
In this work, an investigation has been made in to the performance of latent variable MPC (LV-MPC) in the specific application of reactor temperature control of an exothermic batch process. The paper analyzes the LV-MPC control law derivation and its performance within a batch application. The article considers both constrained and unconstrained applications.

Model Predictive Control for Batch Processes: a Latent Variable Approach
A novel multivariate model predictive control strategy (LV-MPC) for trajectory tracking and disturbance rejection for batch processes, based on multiway PCA models, is presented. It directly computes the manipulated variable trajectory adjustments over a future horizon using the structure of the PCA model. The advantages and the modest data requirements are illustrated using an emulsion polymer...
متن کاملLatent Variable Modeling of Batch Processes for Trajectory Tracking Control
Latent Variable Modeling (LVM) of batch processes is explored from the view point of its application to trajectory tracking model predictive controller design. The ability of the models to capture nonlinearity and time-varying properties of batch processes and to provide a well-behaved description of the process are important characteristics to be considered. Furthermore, the importance of requ...
متن کاملHybrid fuzzy model-based predictive control of temperature in a batch reactor
Processes in industry, such as batch reactors, often demonstrate a hybrid and non-linear nature. Model predictive control (MPC) is one of the pproaches that can be successfully employed in such cases. However, due to the complexity of these processes, obtaining a suitable model is ften a difficult task. In this paper a hybrid fuzzy modelling approach with a compact formulation is introduced. Th...
متن کاملTrajectory tracking in batch processes using latent variable models ?
The set-point tracking of certain process variable trajectories is often needed for the lower level control in batch processes so as to achieve desirable final product quality for the higher level control. In order to realize trajectory tracking successfully, process models should be known in advance. In fact, process models play an essential role in trajectory tracking. Due to the difficulty f...
متن کاملBioaffinity Based Immobilization of Almond (Amygdalus communis) b-galactosidase on Con A-layered Calcium Alginate-cellulose Beads: Its Application in Lactose Hydrolysis in Batch and Continuous Mode
In this study, immobilization of partially purified almond (Amygdalus communis) β-galactosidase on Con A layered calcium alginate-cellulose beads was investigated. Immobilized β-galactosidase retained 72% of theinitial activity after crosslinking by glutaraldehyde. Both soluble and immobilized enzyme exhibited the samepH and temperature optima at pH 5.5 and 50ºC, respectively. Howev...
