If you’re building a moving thing with a microcontroller, you’ll probably want to throw a servo controller in the mix. Driving a servo or two with a microcontroller takes away valuable cycles that ...

The 3C20 digital motion controller from Mesa Electronics is a DSP-based single-axis dc servo motor controller/amplifier for small (up to 100-W) brush motors with quadrature encoders. The device ...

Monitoring takes the form of sensors and intelligent devices connected to a digital processor. These monitored values are used for computing and then controlling some sort of real-world action. Many ...

A very fast digital current controller with an enormous bandwidth for optimal motor current/torque control. The drift-free yet extremely dynamic speed behavior enables a speed range of 1 to 150,000 ...

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.

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 ...

The recent trend in has been to reduce cost, size and complexity of servo systems while increasing performance. High-end machining has always used the best the industry had to offer, but increasingly ...

Hobbyists, developers and electronic enthusiasts searching for an easy way to control up to 12 servos from a PlayStation 4 controller may be interested in a new piece of hardware called the ServoShock ...
