In servo systems, optimising performance factors such as gain and phase shift is critical to achieving precise control. While modern microprocessors can tune servo drives and motors to balance control ...

Electrical engineers will recognize the Bode plot as a plot of the frequency response of a system. It displays the frequency on the x-axis and the phase (in degrees) or magnitude (in dB) on the y-axis ...

When getting from point A to point B is all you’re worried about, simple step inputs usually suffice. But when your machine’s movement between points needs smooth elegance, then a complex, controlled ...

It is not too often that a tool fails me. Most of the time I have made some mistake, so when a Bode Plot failed to predict an unstable system, I came down with a bad case of myopia. I spent so much ...

For the development of dynamic systems in electrical engineering, control engineering, and even mechatronics, the steady-state response at the output of the system to harmonic excitation (sinusoidal ...

Bode plots – or frequency response graphs – are found in just about every piece of literature for high-end audio equipment. It’s a simple idea, graphing frequency over amplitude, but making one of ...

An editor of a technical magazine once told me that subject matter recirculates every eight months as a method of informing an ever-changing audience. It’s been a while since I addressed Bode plots as ...
