摘　　要：针对大容积反应釜高温生产过程动态响应慢、非线性、时滞性、控温精度高,精确的温度控制数学模型难以建立等特点,为某精细化工企业反应釜工艺设计了基于PLC的反应釜温度控制子系统。该系统主控器采用自整定模糊参数PID控制算法,利用MATLAB/Simulink仿真进行了研究,并与传统PID控制算法进行比较。结果表明:系统超调小,响应速度快,消除了时滞对系统的影响。实践证明,改善了反应釜温度控制系统的动、静态响应性能。According to characteristics of the slow reactions to the strong inertia, time-delay, non-linear, the high precise requirements for the temperate-control in chemical reaction kettle and the difficulties in establishing the exact temperate-control math model, the PLC-based temperate-control sub system in reaction kettle will be built for the reaction kettle techniques in some fine chemical enterprises. Adopting the fuzzy self-tuning PID control algorithm, the main control operator system conducts the research with MATLAB/Simulink and the comparison with the traditional PID control algorithm. The result shows that the system has many advantages such as the small overshoot and a quick response eliminating the time delay＇s influence on the system. The practice shows that the fuzzy self-tuning PID control algorithm betters the static and dynamic functions in responding to the temperate-control in the system.
