• 1. backlash valve: 无游隙阀门 | 升降机无游隙阀门 | 游隙补偿阀
• 2. backlash h valve: 无游隙阀门

• 1.Some faults such as amplifier offset, parameter changes, servo valve backlash and sensor fault are seeded in a virtual way by means of different switches in Simulink.
  通过不同开关的动作来虚拟模拟常见的故障，诸如，放大器漂移、系统参数改变、伺服阀反冲以及传感器失灵等。
