pulse servo

The other is of capstan. To produce servo controlling signal, frequency splitting, sampling and retaining, and pulse duration modulating are decisive techniques.

在录像机伺服控制过程中，信号分频、取样保持和脉宽调制占据主导地位，信号分频直接影响取样精度，而取样脉冲经脉宽调制后的方波信号作为反馈电压直接控制电机。

It is established about servo drive system maths mould, Un-linear scattered about control system is emulated, get pulse transfer function for digit control machine.

并建立了伺服驱动系统数学模型，对此非线性离散控制系统进行了仿真，得出了数字控制器的脉冲传递函数。

And this paper analyze the transformation of the coordinate system in motor control, vector control, and space vector pulse width modulation theory. Secondly, this paper design the hardware part of the AC servo system, including power driver board and DSP control board.

并详细解析了电机控制中的坐标系变换、矢量控制理论及空间矢量脉宽调制理论。二、设计交流伺服系统的硬件部分，包括功率驱动板和DSP控制板。

A kind of the pulse control mode, the drive and motor closed loop, but not to the numerical control system, the feedback device, in a sense, can open loop control called the servo control.

一种采用脉冲控制方式，此种驱动器与电机闭环，但不反馈到数控系统，这种驱动器在某种程度上可称为开环控制的伺服控制。

Combining with the practical applications, the whole servo driving system is controlled by the form of analog quantity pulse command.
