phase locked loop controller for harmonic drive
« on: 14/02/2013 07:49:21 »
Hi to all.

I'm new here! ;;) , but my question is  :

Could we design phase-locked loop (pll) controller for harmonic drive?

recent work had done for "dc drive motor".

Any ideas please?

regards

It's not clear what application you are thinking of....
  • You can control the position and speed of a motor by using a stepper motor or a sensor on the drive shaft
  • If there is a harmonic drive on the motor's shaft, this will change the speed and torque of the motor. You could use a position sensor on this shaft.
  • If you know the gear ratio of the harmonic drive, then you can use a frequency divider with that same ratio in the PLL to control the motor position.
