Disturbance rejection, like command tracking, is usually expressed graphically. The graphs, called disturbance rejection plots, show the effect of PIV gains on disturbance torque applied to the shaft ...

As machine builders push for higher throughput, tighter control accuracy, and smaller footprints, the selection of servo ...

Any aviation buff is well aware of the Wright Brothers’ role in the history of flight. But it’s likely that many can’t identify the Wright’s seminal contribution: aerodynamic control. When their plane ...

To correct oscillations in a machine,mechanical design improvements and electronic filters are typically employed.However, these solutions often deliver limited success. Engineers should ...

An industry shift to servo controls for backhoes was one equipment manufacturer JCB bought into. The softer pushing and reduced arm throws required on servo controls led to a reduction in operator ...
