Abstract :
A microprocessor-based slope-varied digital pumped controller (μP-SVDPC) for adapting the system locking performance of the digital pumped phase-locked servo system (DPPLS) is presented. The μP-SVDPC can adaptively provide an optimal-controlled voltage against the coming phase-error for system locking processes. Theoretical analysis and computer simulation for modeling, stabilizing, programming, and designing the μP-SVDPC controller and the μP-DPPLS system are described. A prototype of the μP-DPPLS was constructed and studied experimentally, and a comparison of its experimental results with those of the DPPLS demonstrates the validity of the theoretical results, which predicted a smaller risetime, a shorter settling time, and excellent stability
