摘　　要：在工业生产中,连续搅拌反应釜(Continuous Stirred Tank Reactor, CSTR)温度控制系统存在非线性、强耦合、时变性的特点,反应机理复杂,难于建立精确模型。针对此问题,采用不依赖精确模型的自抗扰控制方案,在PCS7系统上使用SCL语言编写此控制算法,生成易于调试的FB功能块,并在多功能过程控制实训装置SMPT-1000平台上进行反应釜的温度控制对比实验。实验结果表明,相对于传统PID控制,自抗扰控制使系统响应有所增快,超调量减小,并且具有更好地自适应性和抗干扰能力。In industrial production, the temperature control system of Continuous Stirred Tank Reactor(CSTR) has the characteristics of nonlinearity, strong coupling and time-varying, and the reaction mechanism is complicated, so it is difficult to establish an accurate model. In order to solve this problem, an active disturbance rejection control scheme that does not rely on accurate models is adopted. The control algorithm is written in SCL language on the PCS7 system, and the FB function block that is easy to debug is generated. The multifunctional process control training device SMPT-1000 platform A comparative experiment of temperature control of the reaction kettle was carried out. The experimental results show that, compared with the traditional PID control, the ADRC makes the system response faster, reduces the overshoot, and has better self-adaptation and anti-interference ability.
