At unity gain of 12k radians/sec, the open-loop phase is –101°. Thus, the closed-loop system’s phase margin is 79°. The open-loop phase passes through –180° at 6.3k radians/sec. The gain at this ...

The speed current double closed-loop direct current (DC) speed regulation system is a widely used DC speed regulation system, which has the advantages of a wide speed regulation range, good stability, ...
