摘要
针对温度控制系统的大滞后特点,介绍一种双模糊控制方法。通过Matlab/Simulink仿真,其结果表明,与传统PID控制和普通模糊控制相比较,双模糊控制对大滞后、时变、非线性、无法精确获得数学模型的控温系统具有良好的控制效果。该控制方式在快速性、稳态性及准确性方面都有较大提高,较好地解决了快速性与小超调量之间的矛盾。
Aiming at the characteristic of large time delay in temperature control system,a double-fuzzy control method is introduced.The result of the simulation with Matlab/Simulink shows that in comparison with traditional PID control and conventional fuzzy control,double-fuzzy control has better control effect in temperature control for large time delay,time-varying,nonlinearity,etc.The control mode was remarkably improved in the aspects of rapidity,stabilization and accuracy.It solves a contradiction between rapidity and small overshoot.
