基于神经网络的多联变频空调电子膨胀阀控制系统研究

BP-PID control for electronic swell valve of multi-interrelated frequency conversion air-condition

空调制冷系统具有滞后大、非线性等特点,采用普通控制方式时效果不尽人意。采用BP-PID控制器对系统电子膨胀阀开度进行控制,并设计了BP-PID控制器。实践结果表明,该控制方法简单有效,很好地满足了用户的实际需要。

Refrigeration system of air- condition has some specialties, for example, time delay etc, it is difficult to satisfy actual needs by means of adopting ordinary control methods. The paper presented a BP - PID method to control electronic swell valve of system, then BP - PID controller was designed. Experimental result indicates that the control method is simple and effeefive, satisfing the requirement of different consumers.
