过程控制专家研究的热点之一由于其自身存在滞后、非线性特性及控制系统比较复杂的特点系统状态、系统参数和控制算法都直接影响控制精度，经典的PID控制显然很难达到较好的控制效果。模糊控制作为一种经典的智能控制方法,只要设计合理,一般能达到较满意的控制效果。-Process control experts to study one of the hot, because of its lag, non-linear characteristics and the characteristics of the control system is more complex the system state, system parameters and control algorithms have a direct impact on the control precision, the classical PID control is obviously very difficult to achieve good control effect. Fuzzy control as a classic of intelligent control methods, as long as the design is reasonable, generally can achieve satisfactory control effect.
