THE ROBUST, ACCELERATION LOOP SPEED SERVOS

This paper deals with the problematics of acceleration loop speed servos with a subordinate acceleration controller. The acceleration signal is generated by the analog speed sensor, using the
averager and differentiator. The using an acceleration loop in speed (and position) control circuit we are able to achieve better qualities of such circuit. This solution has properties of robust system. The solution is suitable to meet the requirements for a wide range of rpm regulation, run uniformity as well as the devices featuring either non-stationary or extremely high load inertia moment.
