With closed-loop control, poor performance typically manifests itself as deviations from set point. By analyzing these deviations, one can determine if they are caused by suboptimal controller tuning ...

If you look at the block diagram on this page, you'll see there are five elements of an observer: the two inputs - the actual sensor output (Y) and the power converter output (plant excitation) PC - ...

Closed-loop control of these valves ensures an accurate, stable and linear flow rate without hysteresis. Repetition accuracy is rated at +/-0.25% of setpoint. These valves have a peak particle size ...

Flow divider or divider/combiner valves are applied in closed loop hydrostatic transmission applications with an over centering pump and multiple motors to aid traction recovery in the event one or ...
