Abstract :
A microprocessor-based slope-varied frequency-pumped controller (μP-SVFPC) for improving the system locking performance of a frequency-locked position servo (FLPS) control system is presented. The μP-SVFPC is designed to build the controlled voltage by varying its pumping slope identified by the frequency error. With the slope-varied frequency-locked technique, the system acquisition times for short-, middle-, and long-distance servomechanisms have been improved, and are nearly the same
