阀控制器

On the contrary, when the balcony door is closed, sensor A and transmitter B remerges,then transmitter B emits signal to the receiving controller C,at that moment,air-conditioner works normal again for the loop of two-way valve connects controlled by circuit switching.

反之，当阳台门关闭，感应器A、发射器B重新合并，发射器B发射信号至接收控制器 C，通过电路转换控制二通阀回路接通，空调恢复正常工作。

This method requires heating and cooling on the same platens. This controlled cooling is done with special "ramping" controllers coupled to solenoid valves on the cooling system.

此方法要求采用同一压台同时带有加热和冷却功能，此控制冷却功能是通过同冷却系统的螺旋阀相联接的特殊&斜线&控制器实现的。

Periodic fluid pulsation in aeroplane hydraulic piping could induce fluid-construction vibration and lead to fatigue damage. It is impossible to find the error sensor's optimization location because of the pressure standing wave, and the pulsation attenuation effect is not perfect when adopting pulsation attenuation at single point. For this reason, a distributed active control method of fluid pulsation was presented. To avoid stationary point in all aviation states, several fluid pulsation actuators and error pressure sensors were placed along the piping. The second fluid pulsation produced by actuators can counteract the primary pulsation brought by aviation piston pump and make the mean pulsation of whole piping minimum when adopting adaptive feed- forward control and the filtered-X least mean square algorithm.

针对飞机液压能源管路系统中的周期性流体脉动诱发流固耦合振动，导致管路疲劳损伤的问题，针对管路中存在压力驻波特性，在采用单点消振时寻找误差传感器最佳布局位置困难而引起脉动抑制效果不理想的缺点，提出了一种分布式流体脉动主动控制方法，即沿管路不同位置布置多个主动消振阀和误差压力传感器，在任意飞行阶段，避开压力驻波点，以误差压力传感器的脉动测量值为控制目标，采用一种针对周期脉动主动控制的自适应前馈控制法和多通道自适应滤波－X LMS算法，调整控制器参数，使主动消振器产生的次级脉动与管路中的初始脉动相互抵消，达到整个管路中的平均流体脉动最小的效果。

The controller controls the velocity of swing motor by the means of meter-in to track the output velocity of rotary stage of the optimal regulator, so that the load sway can be controlled during swing operation.
