| Abstract: | An AC variable frequency speed regulation experimental platform based on PC is designed.The man-machine interface is developed in Visual C++ environment,in which several control algorithms(including SPWM,SVPWM,DTC,FOC,and so on) are implemented,and the control algorithms can be switched between one and others easily.The control system is designed as a motion card with DSP2812 as the core,and is developed through DLL.The data curves can be displayed dynamically in the progress of experiment on man-machine interface.The working state of this system is analyzed when using the control algorithm of FOC.The experiment results indicate that this system developed can meet requirements,and is practical. |
