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 ...

In a nonlinear world, the challenge of advanced loop tuning is to keep continuous and batch processes, as well as discrete operations, functioning cleanly and productively without unplanned downtime.

How Stable is your Op Amp or FDA design? One of the most important aspects of any end system design is to understand and improve (if necessary) the nominal phase margin for each stage. Since the early ...

The force signal from the strain gage in the load cell feeds back to the motor-drive amplifier, forming a closed-loop force-control system. Industrial applications such as welding, grinding, and ...

Switching power supplies rely on feedback control loops to ensure that the required voltage and current are maintained under varying load conditions. Design of the feedback control loop influences ...

Current-feedback (CFB) op amps have earned their reputation in many applications that need bandwidth, without compromising other noise and high-speed characteristics. They have served these needs ...
