[Abstract]:Nowadays, the level of petrochemical production automation is developing very rapidly, and the demand for industrial control systems in factories is becoming increasingly strong. Therefore, for petrochemical production units, it is easy to develop and realize. Also can control the effect of complete sets of systems, is of great practical significance. Based on the analysis of the inaccuracy of pH control in the process of chemical plant reactor production, as well as the problems of lag and delay, a control algorithm is developed and applied to the pH control of reaction kettle based on the control platform Experion PKS. Firstly, according to the development and current situation of DCS at home and abroad, the development of reactor control is understood. Then, the characteristics of reactor control are analyzed and the design and selection of each device are carried out. Then the control algorithm for pH value of reactor is studied, the characteristics of traditional PID control algorithm and fuzzy control algorithm are studied, analyzed, compared and designed to combine fuzzy control with traditional PID control to form a new control method. Secondly, the whole hardware structure of the reactor control system is analyzed, the hardware selection of the control system and the configuration of the data points are introduced, and then according to the requirements of each control subsystem, The Experion PKS system is used to configure each subsystem of the reactor control system, and the specific control and design of each subsystem are completed. Finally, the pH value of the reactor is programmed on the Experion PKS platform. The pH control algorithm of the reactor is realized on Experion PKS by using the function module of pH control. Finally, the application of pH control in chemical industry to Experion PKS control platform is solved.
