The Flow Ratio Process Control System Design Based on Improved PID Algorithm
Abstract:
This paper mainly introduces a conventional PID algorithm quantity ratio control system. With regulators for control center, combined with the sensors, flow meters, actuators, analog input channel, analog output channel, explosion-proof gate of equipment such as flow ratio control system, to two different liquid flow for example, its characteristic is to keep the Lord flow and vice flow ratio must be objective. The ratio of the calculation of the parameters calculation after all set up changes no longer, in the control system of main and auxiliary loop set respectively, Lord control device that guarantee the ratio of output Settings coefficient and characterization of product quality index the controlled variables is constant, through the practice and the simulation results show that the system can not only meet the technological requirements, and with high control accuracy and stability.
