Abstract

A dynamic model of the evolution of the temperature of a batch cooling crystallizer has been used for the development of a Generic Model Control (GMC) system: for the crystallizer. This servo-control system has been found experimentally to work adequately. The crystallizer has also been controlled with a conventional PI controller, and the process has been simulated with the model. Simulations are accurate enough to allow the model to be used for the design of control strategies for programmed cooling crystallizers. The methodology described can be adapted to the study of other systems or control algorithms.

    Cott and Macchietto [12] applied GMC strategy as controller to track the reactor temperature set point. Vega et al. [42] applied GMC controller experimentally and by simulation to a batch cooling unseeded crystallization process to control crystallizer temperature. Aziz et al. [11] used GMC to design a controller for a batch reactor to track the optimal temperature profiles.

    The models may also contain some empirical features or they may be completely empirical. Reported applications of GMC include grain drying, distillation, batch reactors, pH, crystallization, and a blast furnace [2,3,5,9,10,15,19,25–27]. PMBC is also based on a nonlinear process model, based on fundamental laws of mass, momentum, and energy conservation.
