Closed-loop Behavior of Nonlinear Model Predictive Control

Model predictive control (MPC) relies on real-time optimization to determine open-loop control profiles and state estimates given process measurements. When the underlying process model is nonlinear, the MPC system exhibits unique behavior not seen in linear MPC. In this article, we highlight some of the characteristics of nonlinear models in the context of closedloop performance. We examine th...

Closed-Loop Wastewater Recycling

1 By Keith Dunne and John F. Russo C losed-loop water recycling is only one of several alternatives available when converting. to aaueous or semiaqueous cleaning. Most CFC users have been accustomed to operating a mature and well-defined process. Conversion to other cleaning technologies has forced users to develop entirely new skills and to develop a good working knowledge of the chemistry of ...

Predictive Closed Loop Transmitter Power Control

In this paper, a predictive closed power control loop for mobile communication systems is simulated. The system parameters are derived from those used in a CDMA system uplink transmission at urban mobile speeds. This presents no restrictions, however, on using the proposed method in any closed loop control system where the total received power level is to be estimated from noisy measurements. I...

Predictive Control of a Wastewater Treatment Process

The paper deals with the design of a predictive controller for a wastewater treatment process. In the considered process, the wastewater is treated in order to obtain an effluent having the substrate concentration within the standard limits established by law (below 20 mg/l). This goal is achieved by controlling the concentration of dissolved oxygen to a certain value. The predictive controller...
