While the long term behaviour of a stationary stochastic process is concisely summarized by the probability density function (PDF), many well-established regulatory control techniques focus only on two quantities derived from the PDF, the mean and variance, as key design targets. This paper presents...
Practical process control system design is not applied mathematics. It is about how to put instruments and actuators on the P&ID and FDS for the plant, which are sufficient to make the plant approximate steady state (or more likely a number of reasonably steady states). It is also linked ...
A journal ofIFAC, the International Federation of Automatic Control This international journal covers the application of control theory, operations research, computer science and engineering principles to the solution of process control problems. In addition to the traditional chemical processing … ...
Traditionally, process design and control system design are performed sequentially. It is only recently displayed that a simultaneous approach to the design and control leads to significant economic benefits and improved dynamic performance during plant operation. Extensive research in issues such as 'in...
