| Introduces the application and background of the sing le chip micro-computer controlled and micro-stepping driving of stepping motor and the theory of the whole system and its key technology in detail. Describes the micro-stepping driving of stepping motor and micro-computer controlled gov ernor of turbine this paper. Illustrates that the micro-stepping driving is an effective method for improving the resolving power and eliminating the oscillati ng of low-frequency. The pulse-width modulated micro-stepping of fixed freque ncy is presented, which resolves the technical question of low efficiency. The m icro-computer controller as 80C196 resolves all kinds of questions about contro l technology. The structure of the whole system is simple. If the software is ch anged, it can realize the all kinds of control functions. The experimental resu lt shows that it can highly improve the performances. |
