摘要
PID控制以其算法简单、实用性强而广泛用于工业过程控制。但是,由于被控对象的复杂性使得PID的控制精度和鲁棒性较差。为了提高PID控制的在线自投用率,本文结合在线辨识和模糊推理,提出一种新型模糊PID自适应调节器。
PID controller has been widely used in process controls because of its simple algorithm and powerful applicable features, while the control accuracy and robustness decrease when the con- trolled objects become complicated. To increase the on-line availabil- ity of PID control, the paper stated a new fuzzy self-adaptive PID controller by combining on-line recognition and fuzzy inference.
