MODEL-BASED DESIGN APPROACH FOR DEVELOPMENT PROCESS CONTROL SYSTEMS OF HAZARDOUS INDUSTRIAL FACILITIES

Abstract

The implementation of the "model-oriented design" approach for solving the problem of creating process control systems of mining enterprises is presented. The "model-oriented design" approach is to organize a test loop in which the test object functions in an environment identical to the actual process, in terms of input signals. The approach is based on the use of mathematical models that simulate the functioning of the technological process under the control of the process control system. Mathematical models are used to form sets of test data. A simulation software and hardware complex was developed. The main parts of the complex are: SCADA operator workstation, model operator workstation, data transmission layer, physical signal generation unit, physical signal duplication unit and programmable logic controllers of the process control system. As a simulation environment, the MTSS system is used. A variant of the development of the Hardware-in-the-loop method, which provides the creation of compatible components of automation systems, is proposed and implemented. The description of the method of testing the process control system is given. This technique has been successfully applied to the development, debugging and testing of the automated system for monitoring and controlling a technological object in explosion-proof design.
