摘要
文中结合多点多炉炉温控制实际工程,提出了一种基于模糊迁移与模糊自适应的模糊PID控制器及其设计方法,介绍了双闭环条件下两种模糊PID控制的无缝切换,通过比较仿真分析与实际控温效果,结果表明,与传统PID控制器比较,文中介绍的双闭环模糊PID控制器在对大滞后,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,同时控制系统的鲁棒性大为提高,超调量大为减小,动态抗干扰能力得到增强,较好的解决了快速性与小超调量之间的矛盾。
This paper proposed a double fuzzy-PID controller, which based on fuzzy-transfer PID and fuzzy- self-adaptive PID control algorithm, expounded the design method, and introduced the auto switching method between the fuzzy-transfer and the fuzzy-self-adaptive control mode in the multi-point, multi-stove temperature control system. To compare with the simulative result and the result in practice, It showed the double fuzzy-PID controller, which can achieve a good control performance in the nonlinear temperature system with time-delay, time-difference and unknowable precise mathematical model. The robust performance of the double fuzzy-PID control system is better, the overshoot is smaller, the ability of rejecting disturbance is larger than the tradition PID controller. It can resolve the conflict between quick response and smaller overshoot.
