DSP控制直流电动机的嵌入式软件设计

Design of embedded software controlling DC motor using DSP

自DSP出现以来,电机控制就是DSP主要应用领域之一。特别是随着控制理论的发展和高性能控制的需求,一般的单片或多片微处理器不能满足复杂而先进的控制算法时,更使得DSP成为这种应用场合的首选器件。随着计算机进入控制领域,以及新型的电力电子功率元器件的不断出现,使采用全控制的开关功率元件进行脉宽调制(Pulse Width Modulation,简称PWM)控制方式已经成为绝对主流。这种控制方式已作为直流电动机数字控制的基础。

Since DSP is available, motor control is the main application of DSP. Especially with developing of control theory and high performance control, common single chip or multiple chip microprocessor can no longer meet the need of complex and advanced control algorithm. Thus DSP has become the principal device for these applications. With computer＇s using in controlling, and the coming up of new electronic power devices, PWM（Pulse Width Modulation） control manner by using switch power devices has gained its domination. This control manner has already become the foundation of DC motor digital controlling.
