Two design problems at different levels in the control hierarchy are considered; optimization of robust low-level controllers with constrained control signal activity and optimization of economical high-level polyethylene grade changes. As for the first design problem, a constraint on control signal activity due to measurement noise is presented and used when optimizing and comparing PI/PID con...

This article reviews the use of information from animal-based monitoring systems, management information systems (MIS) and decision support systems (DSS) in pig production. As technology evolves, more and new types of data can be automatically collected. This increases the pace at which new systems are being developed. The collected data are processed into information, which should be used at t...

The ring bus configuration, a topology commonly used at transmission voltage levels, can provide significant enhancements in system reliability and improvements in operating procedures, while remaining an economical and cost-effective design. This paper analyzes the enhancements in reliability and improvements in operating procedures afforded by incorporating the ring bus topology at the transm...
