修正率一说欠妥
对于模拟舵机, 它每次接收控制信号(来自接收机或是陀螺仪)后去修正舵臂位置, 所以控制信号频率等同修正频率
但是数字舵机不是这样的

The theory
With analogue servos the frequency of the control pulse (aka frame rate) affects the operation of the internal electronics which in turn affects the voltage that is applied to the motor terminals. Increasing the frequency of the control pulse often affects the frequency and thus average current at the motor windings which may be considered as making the servo working harder than intended. Other undesirable behaviour may also manifest at these higher frequencies depending on the electronic design.
Unlike analogue servos, for most digital servos the frequency of the control pulse has no negative effects to the servo. The control pulse is simply a position command which the servo controller reads. The process that drives the motor runs independently and thus the frequency and current at the motor windings remain unaffected. |
