sampling servo-mechanism

On the structure of the controller, embedded DSP acts as core processing unit to deal with data sampling, calculating, processing and outputting controlling current to control the action of braking pressure-servo-valve.

在控制器的结构实现上，采用了嵌入式DSP作为核心处理单元，实现数据的采集、计算和处理，并输出控制电流来控制刹车压力伺服阀动作。

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。

The servo driver circuit and sampling circuit are important to the controller. The analysis of servo driver circuit is completed by simulation.

论文着重分析了伺服驱动电路、采样电路的设计，并对伺服驱动电路进行了仿真分析。
