【Abstract】 In order to improve the dynamic and static performances of frequency conversion speed control system, simplify the software and the hardware to produce SPWM wave, a digital frequency conversion system is constituted based on the industrial motor control 16 bits micro-controller 87C196MC. Perfected the fault protection function by using microcomputer’s abilities of fault detection, inquiry and diagnosis. The analysis and the experiment show that the main harmonic is under the suppression, the system has the high stability and the reliability.更多还原
