摘要：

A phase-controlled oscillator (PCO), composed of an adaptive digital-pumped controller (ADPC) and a voltage-controlled oscillator (VCO), is proposed as a novel stepping motor driver. Therefore, a phase-locked stepping servomechanism (PLSS) is established and the PCO can provide an accurate and stable pulse train to adaptively drive the stepping motor. System modeling, analysis, stability investigation, design, and implementation are all conducted. Computer simulation and experiment result indicate that the performance of the PLSS is close to the theoretical prediction. Some speed responses for 40-1000 r/min are examined in the real PLSS. A good speed regulation of +/- 0.15 r/min is achieved. An adaptive line density selector can be used to improve the system performance.
