Abstract: This work addresses the issue of performance evaluation of advanced control algorithms which are going to be implemented on scalable industrial computer networks. The basic characteristic of these implementations is that information concerning measurements from sensors, commands to actuators and reference inputs is exchanged between the plant and the control system over a real-time communication network. The need to evaluate the performance of such algorithm implementations before commissioning them derives from the fact that the network-induced delay during the exchange of the sensor-to-controller and controller-to-actuator data and the possibility of loss of a data package during transmission may affect the algorithm performance. One way of assessing this performance is by emulating the operation of the algorithm on a test-bed. As test-bed is defined the facility that consists of a computer-based simulation of the plant which is linked to the real communication network and actual control devices on which the algorithm will be implemented. As there are many proprietary and open communication network protocols and standards, unavoidably the test-bed has to be constructed for a specific protocol and standard. In this work a test-bed based on the Profibus standard and its FMS protocol has been realized. The purpose is the evaluation of a control algorithm which will run on one or more controllers that will be inserted in an already operating networked control system. In order to demonstrate the way of using a test-bed for evaluating the performance of a control algorithm the study of the LQC control of a cement milling circuit is presented. (More)
