摘　　要：在连续退火模拟实验机温度控制系统的开发中,针对系统的非线性、时变性、变结构、多层次和大滞后等缺点,引入模糊专家系统的结构和理论基础,并结合实际调试过程中总结出的专家策略,即采用分段PID控制方法和动态变结构控制方法相结合的控制策略,建立了模糊专家温度控制系统.实验结果表明,该控制系统控制效果好,温度超调量小,针对不同尺寸规格试样的控制性能稳定,适用范围广,达到了冷轧带钢连续退火模拟实验机温度控制系统的设计性能指标.According to the disadvantages of the continuous annealing simulator＇s temperature control system, such as nonlinearity, time-varying, variable structure, multi-level and long time delays, an expert system of fuzzy temperature control was developed via introducing the structure and theoretical basis of fuzzy expert system in combination with some expert control strategies generalized from actual debugging process, i.e., combining the sectional PID control with dynamic structure-varying control. Testing results showed that the control system is effective with low temperature overshoot, steady controllability for the specimens of different sizes and wide scopes of applications. Thus, the temperature control system comes up to its performance indices designed for the continuous annealing simulator to cold strips.
