    Determining first order process parameter

    1. Ackermann / symbolic method So the Ackermann method is also applicable for the "quasi time-continious" PID-approach. 2. CLTF with K ... Look at the thread http://groups.google.com/group/sci.engr.control/browse_thread/thread/49ab4f796f72c43a/974313257b23abc4?#974313257b23abc4 at...

    Determining first order process parameter

    Hello, Im starting the discussion again. At first, I will recapitulate some points, we talked about in the past and they were not completely clear for me. 1. For calculating the PID-controler-gains you talked from a "Symbolic method" and the "Ackerman method". Further you said, that the...

    Determining first order process parameter

    Hello Peter, sorry - but I saw your reply just now. I will yet test the parameter detection by a testdrive and the least-square-error methode to get the parameters Tau and K. I think this is your favourite... Wolfgang

    Determining first order process parameter

    Hello, "Can you use K and tau in the gain calculation formulas and calculate gains that work?" yes K ist the quotient of velocity/current. the Velocity is a value which is 8,192 times higher than the value in rpm speed = 8,192*rpm and current has the range from -32767 to 32767 which is...

    Determining first order process parameter

    Hello Peter, You got the Impulse-reaction of the motor with an brake (to get a higher inertia - the braking effect is near zero). It was the green marked line at http://www.loaditup.de/345634.html At this sheet I was astonished, that the curve of the impulse response didnt have a typical...
