Control Structure Design in Process Control Systems
The control configuration problem is discussed. A new algorithm is outlined which gives suggestion on feedback and feedforward control structure given a SISO control loop and some extra measurements. The algorithm is based on simple experiments and leads to a model of the process as a directed graph. The method is illustrated on a few common industrial control problems. Copyright c & 2000 IFAC
متن کاملProcess Modelling in Control Systems
Process modelling is the formal description of the activities undertaken by an organisation. By modelling such processes we can support and improve these activities. Taking a control system development project as an example, we describe how process modelling can be integrated into an EXPRESS based environment using the EXPRESS-P extension to EXPRESS. In order to capture some important aspects o...
متن کاملHybrid Systems in Process Control
Modeling and control of hybrid systems, with particular emphasis on process control applications, are considered in this article. Based on a number of observations on typical mixed discrete and continuous features for such applications, a fairly general model structure for hybrid systems is proposed. This model structure, which clearly separates the open loop plant from the closed loop system, ...
متن کاملA Method to Justify Process Control Systems in Mineral Processing Applications
The impact of installing process control systems can be expected in terms of performance improvements through reduced operating costs. Since these installations impose considerable capital expenditure, the profitability of the new systems should be economically justified. Controlled variable trend was reconstructed by a combination of simple waves, which provided a means to simulate the ef...
متن کاملJava for Real-time Process Control Systems
This paper investigates the temporal behaviour of the Java run-time environment for real-time control system applications. A representative process controller is used as a case-study, and has been implemented in Java according to a number of proposed generic software architectures. These are assessed upon several general purpose run-time platforms, before extending the investigation to a claime...
