摘要
加热炉温度控制系统具有大惯性、大延迟和时变等特性,采用常规控制方法的温控系统难以获得满意的控制效果。结合定量反馈理论(QFT)和模糊控制以及传统PID控制的各自优势,对控制器进行设计。仿真结果表明,所设计的控制器能够很好地解决由于加热炉温度控制系统模型参数具有不确定性而造成的控制系统鲁棒性设计问题,以及能根据被控对象不同工况变化的要求,获得满意的动态和静态控制特性。
The temperature control system for heating furnaces is characterized by such features as a big inertia,a long delay and time variation etc.It is difficult to achieve satisfactory control effectiveness for a temperature control system by adopting the conventional control methods.By making use of respective advantages of the quantitative feedback theory,fuzzy control and traditional PID(proportional,integral and differential) control,a controller was designed.The simulation results show that the controller be...
