连续搅拌釜式反应器是合成材料、制药、油漆、燃料、农药等化工生产过程中应用非常广泛的设备，在反应装置中占有重要地位。连续搅拌釜式反应器系统中最重要的参数是反应温度，温度的控制品质直接影响产品质量和产量。目前自动控制领域专业技术人员提出了多种可行的控制方案，满足了生产过程的基本要求，但有些温度控制方案并没有充分发挥控制装置和控制系统的潜力，在控制性能方面存在很大的改善空间。 课题主要研究如何高效率地利用夹套及蛇管冷却装置实现连续搅拌釜式反应器系统的温度控制。双重/阀位——串级控制方案一方面利用蛇管冷却的快速性，及时消除偏差，使系统具有良好的动态特性；另一方面利用夹套冷却效率高、经济性特点，使系统具有良好的静态特性，节能降耗。 双重/阀位——串级控制方案中，主控制器选用仿人积分控制算法。经过研究发现这种算法存在不足，故进行改进并提出保持型仿人PID控制算法及控制器参数的工程整定方法。 将保持型仿人PID算法应用于双重/阀位——串级控制方案中，经过仿真，温度超调量较小、调节时间较短，抗干扰能力较强，具有一定的应用价值。

Continuous stirred tank reactor playing an important role in chemical production process, is widely used in synthetic material, pharmaceutical, paint, fuel, pesticides etc. The most important parameter of the reactor system is temperature, which affects product quality and output directly. Currently, professional staffs and technicians made various possible programs to meet the production process. However, some projects haven’t played the potential of equipment and control systems fully. There have great improvements in control performance. How to use the jacket and coiler achieving the goal of temperature control efficiently is studied. On one hand, Dual or valve position-cascade control system eliminates error timely taking advantage of coiler‘s high-speed and than the system has better dynamic characteristic. On the other hand, with the help of jacket’s efficiency the system is provided with excellent static property and energy-saving. The main controller of dual or valve position-cascade control system selects human-simulated integral control algorithm. After studying, the shortage of this algorithm has been found, as a result, retentive human-simulated PID control algorithm and its controller parameter tuning method is advanced. The algorithm is applied into dual or valve position-cascade temperature control system, after simulating, the temperature have smaller overshoot, shorter settling time, and stronger anti-interference ability.
