It’s easy to take feedback devices for granted. However, the impact this seemingly minor component can have on a system’s ...

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 ...

Sponsored by Texas Instruments: Single-chip microcontrollers geared to servo and other industrial/EV control applications help engineers cost-effectively design multiple-axis systems. As manufacturing ...

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 ...

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 ...

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 ...
