The controller parameters are updated only at sampling instant that is equal to multiple cycle, so continous and rapid controller adjustment is avoided.
控制器参数仅在与采样周期成倍数关系的时刻改变，避免了控制器频繁而剧烈的调整。
The controller make up of TMS320F2812 DSP chip, detecting circuits include sampling circuit, modulate circuit and phase locked loop and other periphery control and drive circuit.
本文设计的控制器以TMS320F2812 DSP芯片为核心，加上检测电路（包括采样电路、调理电路、锁相环等）和其它外围控制和驱动电路构成。
The electric motor permits the use of an electronic controller, and the ability to programme a complete tow in terms of sampling duration before each gauze advance.
