摘要：攪拌器將高溫物料與低溫物料進行混合攪拌，得到一定輸出溫度的混合物料。由于管路延遲很嚴重，采用常規PID控制器超調量較大，反應速度很慢，控制效果不佳。本文設計的攪拌器溫度控制系統采用的是微分先行PID控制器，文中對如何合理選擇被控量、操縱量、控制閥的類型、調節器正反作用以及如何進行調節器參數整定都做了較為詳細的介紹。并從性能指標，抗干擾等方面將微分先行PID控制系統與常規PID控制系統進行比較，并運用MATLAB對所設計的系統進行了仿真。

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.
