| Abstract: | An intelligent frequency converter with PROFIBUS-DP interface was designed by adopting modularization design pattern. DSP chip TMS320F240 is the control kernel of the frequency converting part and the microprocessor of PROFIBUS-DP interface. The communication interface chip SPC3 was applied to construct PROFIBUS-DP slave station in this frequency converter, and intelligent PID control algorithm was analyzed. The technology of PROFIBUS-DP slave station was introduced into AC speed regulation svstem, which has better control character. |
