Stability is important in analog and power circuits. Without stability, control loops can run out of control, leaving you with oscillations and other nasty realities. Power supplies, for example, need ...

After designing a control loop within a power supply, motor drive, or almost any power-electronics product, engineers must establish that they have achieved their target specifications for loop ...

In the electronic field, an oscillator is a circuit capable of producing a self-sustained sinusoidal signal. In a lot of configurations, cranking up the oscillator involves the noise level inherent to ...

It may come as a surprise to some that a control loop’s Bode plot does not always depict the loop stability and that the output impedance measurement, obtained non-invasively, always does. Challengers ...

Every plant in the process industry most likely has several control loops that do not perform well. Although there are many factors that may negatively affect control loop performance, a few of these ...

Only through proper troubleshooting and then solving the underlying problems can control loop performance be improved. Process design certainly plays a role in control loop performance, but experience ...

Pilot-induced oscillation is a frightening aspect of pitch control of an aircraft. Numerous planes have been set into pilot-induced oscillation due to the phase lag of the human in the loop control.
