The internal model principle is a 30-years-young idea that serves as the basis for a myriad of modern motion control approaches. One such algorithm — harmonic cancellation — is indispensable ...

The 4-to-1 frequency ratio applies to the use of standard controllers; motion controllers with more advanced control algorithms can achieve good system control at ratios of about 2-2.5 to 1.

Control algorithms relying on feedback and feedforward methods can achieve impressive performance but come with inherent limitations. Preventative disturbance compensation : Machine learning control ...

In theory, it cannot be ruled out that the algorithms might run for longer than the age of the universe. But in practice, many algorithms seem to work just fine. Almost always.

ACS developed the algorithm to deliver improvements on several fronts. The degree of improvement over existing motion control varies by deployment. "The standard ACS servo algorithm is an advanced PID ...

Implementing the algorithm, though, can get a bit tricky since it touches bits of linear algebra, motor physics, and control theory. But that’s the magic behind SimpleFOC. With the library at ...

A new theory could bring a way to make quantum algorithm development less of an accidental process, say scientists. In 2019, Google claimed it was the first to demonstrate a quantum computer ...
