Controller coefficients
In this chapter you can read about:
Velocity Loop P Term .................................................................................................... 204
D-term of the KD velocity controller ............................................................................... 204
P-term KV position loop ................................................................................................. 204
Dependence of the controller coefficients from the optimization objects
The controller coefficients are influenced by the optimization objects such as
"stiffness" and/or "attenuation". The dependency is displayed below.
