Abstract:

A microprocessor as the core of the digital controller has become one of the major features AC speed regulation system in modern. Based on DSP as the core of the speed control system,it can realize complex algorithm. At the same time, it can achieve the diagnosis of system’s fault, and the self-setting of parameters controlled, etc. Thus it can make the motor speed control system have higher performance. This paper introduces the motor speed control system which consists of three DSP. This system is able to adjust two Frequency conversion motor. Division of work to the DSP is according to the function of DSP. Inter-DSP makes use of dual-port RAM to exchange data and communicate. They work together to achieve and improve the performance of the control system.
