Abstract
A multi-driver control method and an apparatus thereof are disclosed in the present invention. The multi-axis control method comprises the following steps: providing a set of control curves, each curve of the set of control curves controls a driver respectively; dividing the curves by a set time period; sending the divided curves in the same time period to the corresponding drivers in one time period, and sending a unified beat signal to all the drivers in order to synchronize execution time of all the drivers; fitting and restoring a programmed motion curve of each driver according to all received divided control curves; taking points at each driver's own programmed motion curve, which is restored locally, of each driver to control the rotation of each driver's own motor.

A multi-driver control method, which comprises the following steps:
- providing a set of control curves, each curve of the set of control curves controlling a driver respectively;
- dividing the control curves according to a set time period;
- sending the divided control curves in the same divided time period after division to the respective corresponding drivers in one time period, and sending a unified beat signal to each driver to synchronize execution time of each driver;
- fitting and restoring a programmed motion curve of each driver according to all received divided control curves;
- and
- taking points at the programmed motion curve, which is restored locally, of each driver to control the rotation of each driver's own motor.
A multi-driver control apparatus, comprising the following units:
- a curve generation unit, for providing a set of control curves, each one of the set of control curves controlling a driver respectively;
- a dividing unit, for dividing the control curves generated by the curve generation unit according to a set time period;
- a sending unit, for sending the divided control curves in the same time period to the corresponding drivers in one time period, and sending a unified beat signal to all the drivers in order to synchronize execution time of all the drivers;
- a curve programming unit, for fitting and restoring a programmed motion curve of each driver according to all received divided control curves;
- and
- a control unit, for taking points at the programmed motion curve, which is restored locally, of each driver to control the rotation of each driver's own motor.
