Motion-control architecture appears to be compact and simple. But in reality, the individual servo loops-current, velocity and position-have been traditionally shared between a drive and a separate ...

A pivotal review in servo systems engineering underscores a significant leap in motor technologies and control strategies. This research encapsulates the critical advancements propelling precision and ...

Hobby servos are great, but they’re in many ways not ideal for robotic applications. The good news is that [Adam] brings the latest version of his ServoProject, providing off-the-shelf servos with ...

Variable-speed pump drive technology that matches pressure supply to demand is creating the ability for energy-efficient hydraulics to produce energy savings in the range of 30 percent to 80 percent.

From single-cable systems to energy-harvesting encoders, new feedback device features improve accuracy, reduce downtime and accelerate machine commissioning. • Multi-turn absolute feedback via energy ...

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 ...

As manufacturing industry continues to replace manual processes with automated versions, servo motors are replacing pneumatic and hydraulic systems (Fig. 1). It’s resulted in a rapid increase in, and ...

1. Don't fear servos. There are many different levels of positioning and motor controls now. Some basic variable frequency drives can even be used to do what could have been done only with coordinated ...

Servo controllers commonly use traditional cascaded configurations in which a velocity loop is nested within a position loop. This configuration originated when current and velocity controllers were ...

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 ...
