摘要:
本文所分析的是一种作为复合控制系统的锁相倍频器,它在低频宽带运用时具有优良的性能。环路中采用了一种采样一保持型的鉴相器,抑制了普通鉴相器所固有的输出脉动分量,在很大程度上避免了倍频输出中的寄生频率调制现象;同时,低滤通波器的时问常数还可取得很小,甚至完全省去,这样又缩短了捕捉时间。环路中还增设了一种特殊设计的自动增益控制电路,既保证了系统的稳定性,又获得了良好的跟踪性能。文章对所提出的设计原则进行了实验验证。
Abstract:
The phese-lockcd frequevcy multiplier described in ibis paper is a complex control system which has excellent performance in low frequency wide band operation. Since a sample-hold type discriminator is employed in this loop. the output ripple inherent in ordinary phase discriminator is restrained and the parasitic frequency modulation in frequency-multiplied output is avoided to a great degree. As a result, the time constant of low-pass filter can be kept very small, or even be zero, thus cattsing a shortening of the capture time. Also,a specially designed AGC circuit is adopted in this loop that not onlyinsures the system stability, but also gives a good tracking performance. Thedesign principles presented in this paper have been verified experimentally.
