Application flexibility and cost concerns are creating a demand for intelligent power-supply designs that support soft configuration in production and external control. These advanced power supplies ...

Today's microcontroller units (MCUs) can implement the control functions and feedback loops of off-line ac-dc power converters, which do not require extremely fast control loops. As an example, a ...

Many motion applications require high accuracy during and at the completions of moves. Even with perfectly optimized PID (proportional, integral, derivative) values to control position, the ...

Machines and processes are controlled using many strategies, from simple ladder logic to custom algorithms for specialized process control, but proportional-integral-derivative (PID) is the most ...

Can we improve performance by adding control elements external to the PID loop? Yes. Here we consider torque control and the related subject of torque feedforward — which can make systems run more ...
