Hi.
Once a time several years ago I came over some theory about a motor controller. What I remember now is this:
It contains 4 opamps. One integrator, one differentiator and a regular noninverting opamp amplifier stage. Then I think all three stages mentioned above had their input connected together and I also think that the output from the three stages went into a adder circuit.
The input comes from a frequenzy to voltage converter on the motor shaft.
However I don't know what this technique is called and therefore it's impossible to google for it. Anybody knows?
