Abstract :
The practical implementation of minimum-time control of angular position using a permanent-magnet dc servomotor is considered. First an analog time-optimal controller derived from the switching characteristics is discussed. This leads to the digital controller based on the quantization of these characteristics. The use of a suitable digital tachometer makes it possible to reach the theoretical minimum time.
