摘要： A method and system for characterizing pressure controller valves of a pressure controller system are described herein. The pressure controller system includes a first valve and a second valve coupled to a manifold and a controller configured to control operation of the first valve and the second valve. The first valve regulates mass flowrate into the manifold and the second valve regulates mass flowrate released from the manifold. To characterize the apply valve, an electronic solenoid current to the first valve is increased until the manifold pressure rate exceeds the pressure rate threshold. When the manifold pressure rate exceeds the pressure rate threshold, the electronic solenoid current to the first valve decreases until the manifold pressure rate falls below the pressure rate threshold. These steps continue until the manifold pressure exceeds a manifold pressure threshold. At this point, the first valve is closed and characterization of the second valve commences.

摘要翻译： 本文描述了用于表征压力控制器系统的压力控制阀的方法和系统。 压力控制器系统包括联接到歧管的第一阀和第二阀以及被配置为控制第一阀和第二阀的操作的控制器。 第一个阀调节进入歧管的质量流量，第二个阀调节从歧管释放的质量流量。 为了表征施加阀，增加到第一阀的电子电磁阀电流直到歧管压力速率超过压力速率阈值。 当歧管压力速率超过压力速率阈值时，到第一阀的电子线圈电流减小，直到歧管压力速率降到压力速率阈值以下。 这些步骤继续，直到歧管压力超过歧管压力阈值。 此时，第一阀关闭，第二阀的表征开始。
