COMPARISON OF MID-RANGING CONTROLLERS

Mid-ranging control applications are multivariate and often in involve input constraints. Although some strategies have been reported in the literature, no systematic comparison has ever been made. The purpose of this report is to compare these schemes to a model-based predictive control (MPC) approach designed specifically for these types of appli cations. The results indicate that although there are special cases wh ere the existing schemes work reasonably well, MPC is best able to sol ve the problem in the general case.
