基于DSP与IRMCK201控制器的M／T测速方法研究

介绍了TMS320F2812芯片的正交编码（QEP）单元、混合式光电编码器以及IRMCK201控制器的工作原理，并在此基础上运用TMS320F2812与IRMCK201专用芯片相结合设计出控制交流永磁同步电机位置环中所反馈的电机转角，以及用于IRMCK201速度环反馈电机转子角速度大小的采集与计算方法，同时提出在对光电编码脉冲采样时的一些改进。

Study on M/T Speed Measurement Method Based on DSP and IRMCK201 Controller

Introduction was made to quadrature encoding processing (QEP) unit of TMS320F2812 chip, mixed type photoelectric encoder and working principle of IRMCK201 controller. On the basis of this, TMS320F2812 was combined with IRMCK201 special chip to design the feedback motor rotation angle in the position loop control of AC permanent magnetic synchronous motor, motor rotor feedback velocity collection used in velocity loop of IRMCK201 and the calculation method. In the meantime some improvements were raised for p...
