摘要：
A servo system includes multiple servo channels being driven by a common error signal. Each channel has a controller that receives an error signal and provides a drive signal to a driver. The servo channels are arranged serially, with a drive signal from one controller forming the error signal for a downstream controller. As a result, the downstream controller does not attempt to correct for phase error directly, but instead attempts to keep the upstream driver at or near its operational midpoint. The servo channels can be arranged in order of decreasing controller bandwidth, from fastest to slowest. In contrast with a parallel configuration, in which servo channels all simultaneously receive a common error signal, the serial configuration can allow each controller to use its full bandwidth, can eliminate crosstalk between servo channels, and can prevent saturation of upstream drive signals.
摘要（中）：
伺服系统包括由公共误差信号驱动的多个伺服通道。 每个通道具有控制器，其接收错误信号并向驱动器提供驱动信号。 伺服通道串联布置，来自一个控制器的驱动信号形成用于下游控制器的误差信号。 因此，下游控制器不会直接尝试纠正相位误差，而是试图将上游驱动器保持在其操作中点处或其附近。 可以按照从最快到最慢的控制器带宽降低顺序排列伺服通道。 与其中伺服通道同时接收公共误差信号的并行配置相反，串行配置可以允许每个控制器使用其全部带宽，可以消除伺服通道之间的串扰，并且可以防止上游驱动信号的饱和。
