PC-based packages for identification, optimization, and adaptive control

PC-based integrated environments are proposed for identification, optimization and adaptive control of industrial processes. The identification package uses the recursive least-squares method for parameter estimation and the predictive least-squares criterion for order selection. The optimization package concerns the optimal tuning of digital PID controllers, given the discrete model of the controlled process, which can be obtained via the identification procedure. The adaptive control package considers several certainty equivalence adaptive control strategies by combining various control strategies by combining various control strategies with several recursive identification schemes. One representative example, using a real process, is presented to illustrate the effectiveness of the techniques used and the usefulness of the integrated environments.<>
