On the condition that the stability of optoelectronic tracking system is satisfied, higher bandwidths of the speed and current loop should be selected.

因此，在设计光电跟踪系统时，在不影响系统稳定性的前提下应选用尽可能大的速度及电流闭环带宽。

Dynamic large-signal, DC, and small-signal circuit models including parasitic resistances and current ripples of nonideal synchronous rectifier buck converter operating in CCM are established. Closed-loop modeling of nonideal synchronous rectifier buck converter for voltage-mode control is studied. Transfer functions are obtained. Effects of parasitic components on control loop design of the converter are explored. Systematic simulation analysis is performed. All the results show that it is necessary to include parasitic components of converters into equivalent models.
