模糊PID控制在中密度纤维板施胶中的应用研究

PID控制针对单输入单输出的定值线性系统能达到较理想的控制效果,但针对中密度纤维板施胶控制系统,不能很好解决施胶控制中多输入多输出、非线性、时滞等诸多问题.通过比较常规模糊控制器和传统的PID控制器在控制方面的优缺点,结合PID控制中存在的问题与不足,提出将模糊控制技术与PID控制算法相结合构成复合型控制器.经仿真试验,控制效果明显改善.

The application of fuzzy-PID control in the applying glue system of medium density fibreboard

To linear system of single input and single output, PID controller can achieve the better control effect. But it can't resolve the things effectively in the applying glue system of medium density fibreboard, for example: multiple inputs and multiple outputs, non-linear, time lag etc. Through the comparison of the merit and defect of Fuzzy controller and PID conroller, combining with the Fuzzy controller and the PID controller, it brings forward the Fuzzy-PID controller. The result of simulation indicates distinct improvement of control effect.
