Abstract:Stirrer will mix high-temperature materials and low-temperature materials ,and a certain temperature of the mixed materials will output. Because of the delay line seriously, the overshoot of using conventional PID controller is larger, and the reaction is slow, control ineffective.In this paper, the design of mixers used in temperature control system are first differential PID controller, the article on how to choose a reasonable amount charged, and manipulating the volume control valve types, positive and negative role of regulator and how to adjust parameters of the entire capital is in a more detailed introduction. From performance indicators, anti-interference, etc. compare the first differential PID control system with conventional PID control system, and the use of MATLAB for the design of system simulation.
Keywords: Stirrer, the conventional PID, differential prior PID, MATLAB, regulator
