摘要
为了提高三相感应电动机转速控制时的精度。提出了一种基于DSP控制的转速闭环恒压频比控制方法,并对闭环转速控制原理和SPWM波形生成原理及步骤进行了简要的分析,建立了基于DSP环境下的程序流程。
In order to improve accurate rotational speed control of three phase induction motor,bring forward the control way of rotational speed closed constant V/Hz principle, analyzed the principle of rotational speed closed control, SPWM waveform generation principle and steps, set up on the basis of DSP program work flow.
