Research On Control Algorithms For An Industrial Process Experimental System Based On Deltav

An industrial process experimental system based on DeltaV, which is designed in order to satisfy the need of simulating the real industrial process in our laboratory, is introduced and studied in this paper.As an experimental system, the industrial process experimental system based on DeltaV can simulate three types of typical industrial process: the heat exchanger, the SRF system and the three tank water control system. In our experimental system, we can configure different types of control algorithm, such as: PID control, fuzzy logic control, DMC predictive control and relay feedback identification etc.In the project, my work include the control algorithm configuration and the realization part, that contains the control configuration, GUI design, historical data collection and analysis etc, and these construct the main part of this paper. The main content of this paper is:First, the paper specifies the hardware and software structure of the industrial process experimental system, gives the model of the controlled objects (heat exchanger, SRF system and the three tank control system) and introduces the control configuration languages used in DeltaV system.In succession, the paper introduces the control algorithms used in experiment, which include PID control, fuzzy logic control, DMC predictive control and relay feedback identification. The introduction can be divided into two parts: the basic principle of the algorithm and what it is used in our DeltaV system.Finally, the paper discusses and studies the control experiments based on this experimental system. This part is focuses on the controller regulation and the differences among these control algorithms.
