A Review on Process Controllability
نویسندگان
چکیده
Definitions of terms used within process flexibility design and controllability assessment are given and their relations discussed. Methods for controllability evaluation and methodologies for integrating these into the design process are reviewed for some modes of operation. Basically two types of evaluation and design methods prevail; One type is based upon linear model analysis, whereas another type is based upon physical chemical insight and thus provides nonlinear information. In process design practice the plant piping and instrumentation diagram evolves iteratively using mainly experience and process reasoning to address questions related to plant controllability. It would be desirable to be able to address such questions more quantitatively at different abstraction levels during process design such that controllability evaluation can be integrated into the design process. This paper is an unpublished internal report, which is produced within the EU CAPE.NET project (working group 3). Any comments you may have are welcome at: [email protected]

Tools and methods for current and future controllability assessment
Driver related evaluation of Advanced Driver Assistance Systems (ADAS) needs to address controllability, effectiveness and user acceptance, which are to some extend interfering with each other. The state of the art in the controllability assessment is currently defined by the Code of Practice of the RESPONSE 3 project which focuses on the driver-systeminteraction with single assistance function...
متن کاملSimultaneous Design and Control of Nonlinear Chemical Processes: A State-of-the-Art Review
Currently, chemical process design and process control are separate disciplines assisting process development at different stages. Design and control decisions are made separately despite the common objective of dissipating the impact of disturbances and uncertainty to ensure robust plant operations. Nowadays, it is broadly accepted that this is not a desirable situation since this approach can...
