Introduces the application and background of the single 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 governor of turbine this paper. Illustrates that the micro stepping driving is an effective method for improving the resolving power and eliminating the oscillating of low frequency. The pulse width modulated micro stepping of fixed frequency is presented, which resolves the technical question of low efficiency. The micro computer controller as 80C196 resolves all kinds of questions about control technology. The structure of the whole system is simple. If the software is changed, it can realize the all kinds of control functions. The experimental result shows that it can highly improve the performances.
