What is the "delay" on HH gyros

Posted by Ryan Beall on April 13, 2011 at 2:29pm

I have researched a ton on what commercial gyros are doing with the delay setting.  This is used to alleviate the phase lag introduced with the slower servos.  How are they actually implementing this in software? Any help here would be great

    Created a basic simulator to get the general idea of how servo lag affects the tail rotor and phase lag. Sort of interesting project but completely inaccurate, but very helpful to see the basic trends of what to expect. Should be really easy to develop now even if the numbers mean nothing more than general trends!

    Yes, is this, for example, like the delay pot on a GY401 that you're referring to?

    Ryan, that's an interesting question. Can you tell us a bit more? When you say "commercial gyros", what kind do you mean? And how would a gyro know what kind of servos, to say nothing of control loops, an autopilot might use?
