本次设计内容是针对带搅拌釜式反应器(CSTR)温度控制系统非线性、大惯性、纯滞后的特点，基于SCILAB进行控制方案设计。带搅拌釜式反应器(CSTR)温度变化有滞后，常规PID控制的控制性能不佳，需要研究改进的方法。主要方法是运用模糊控制实现对带搅拌釜式反应器的温度控制，解决这个问题需要用到与MATLAB相似的SCILAB，通过该程序完成编写。

SCILAB Based Continuous Stirred Tank Reactor(CSTR)temperature control
Abstract:Due to its low cost, the high ability of heat exchange and stable product quality characteristics, continuous stirred tank reactor (CSTR), as a chemical reactor, has become the core equipment to produce polymer, which has been widely used in the chemical, fermentation, bio-pharmaceutical, oil production and other industrial production process.The control variables of the CSTR include pressure, temperature, concentration, etc, and the control of these variables will affect the quality of the product directly in the chemical production. In actual production process, the CSTR would be influenced by many unfavorable factors, which is difficult to build a precise mathematical model and to realize the performance-oriented control.
The design is directed to a continuous stirred tank reactor (CSTR) nonlinear temperature control system, large inertia, pure lag characteristics, based SCILAB control design. A continuous stirred tank reactor (CSTR) temperature hysteresis, the control performance of conventional PID control is poor, we need to study ways to improve. The main method is the use of fuzzy control of a stirred tank reactor temperature control, to solve this problem and the need to use MATLAB similar SCILAB, to complete the preparation by the program.
Key words: fuzzy control; stirred tank reactor; PID parameter tuning; temperature control; SCILAB
