| Abstract: | In order to improve mierostep control precision, the function ralation between two-phase hybrid stepping motor microstep step pitch vector angle and microstep current was taken as the control wave of microstep current, and the numerical solution was derived for the function. The precision control of microstep current and on-line calculating of microstep current set value was realized. The application in L297 ＋ L298 driving system with this method was successful, and the driving circuit simple and agility of the system was reached. |
