Hi,
My knowledge of motor control is very basic. We are asked to build a system for the control of a camera on two axis. We are required to use a 3 phase AC motor.
The requirements are 1 mrad position accuracy and 180 deg in less than 2 seconds.
Is there an alternative to the use of three loops, current, speed, position ? Can it be more simple ?
Are there ready made ICs or PCBs for the position control of AC motors, or at least for the speed control, providing we can close the position loop with a P controller ?
Regards
