Motion control systems, which normally control the position of actuator or stage, are at times given the task of providing both position and force control. These systems operate in a dual mode, in ...

Hydraulics is great for lifting heavy loads and applying large amounts of force, but the same power that is required to exert a large amount of lifting or compression force can also do damage or ...

The controllers that drive modern motor-powered designs must be set up with accurate motion profiles — including position, velocity, and time targets. However, developing a realistic motion profile ...

The ABCs of PID control. Considerations for interfacing elements in the electrical circuit to accomplish those parts of the PID function for position control. Firmware code implementation.

A brushless-DC motor is common in ceiling fan and pan-tilt-zoom (PTZ) camera designs. But you can’t use the same brushless-DC motor solution for both of these end products. A ceiling fan driver ...

Your quad-copter is hovering nicely 100 feet north of you, its camera pointed exactly on target. The hover is doing so well all the RC transmitter controls are in the neutral position. The wind picks ...
