Damping of a dynamical system

  1. Feb 18, 2016 #1
    How to change the damping ratio of dynamical system if it is say for example robotic arm? Can it be changed directly or one need to change natural freqvancy? by which it will automatically change.

    assuming a second order linear system, the system equations make it pretty clear.


    You can change any system variable, or multiple variables to get different damping and natural frequencies.

    If you want one knob to just change only the damping ratio, that is difficult for a 2nd order linear system.
