本文提出一种身用前馈控制的锁相环。分析表明
这种环路性能良好
精度高
而且不影响环路的稳定性
捕捉特性也有很大改善。文中还讨论了在噪声作用下采用这种环路的可能性和滤波器的设计问题。
A method of complex control of phase-locked loop is presented. Theoretical analysis shows some desirable properties. This method improves not only the working precision without affecting the loop stability
but also the acqusition properties. The possibility of using this kind of phase-locked loop under noise interference and the problems of filter design are discussed.
