【摘要】 越来越多的基于嵌入式数字电机控制(DMC)芯片引入了反馈控制,用于及时记载电机反馈回来的转速和位置,以便进行相应的电机调节和控制,这些特性代表了一种卓越且灵活的PWM发生及系统控制方案。如Siemens的C504,C508单片机,TI的TMS320C24x DSP系列等。本文主要以TI公司的面向电机控制专用的TMS320C241 DSP芯片来讨论其捕获单元的工作原理和设计方法。更多还原

【Abstract】 In order to put down the speed and location of the motor feeding back for its modulation and control, more and more embedded DMC chip introduce feed-back measure. It represent a flexible and excellent system for PWM produced and control. Such as the Siemens’ microcomputer C504 and C508, TI’ s TMS320C24x DSP and so on. This paper introduce the principle and design measure of the Capture Cell, using the motor special chip TMS320C241 for example.更多还原
