Abstract

The present invention is a direction -based motor -driven XY platform contour processing control device and method and method. This device includes AC pressure regulating unit, voltage adjustment circuit, rectification filtering unit, IPM inverter unit, digital signal processor DSP, Hall sensor, Hall sensor, Hall sensor, Hall sensor, Hall sensor, Hall,Grav gallery ruler, current sampling circuit, location sampling circuit and IPM isolation drive protection circuit. The digital signal processor DSP also has a NURBS interpolation, speed field controller, IP controller, and integration.The speed field controller of the direction field theory makes the ruler path completely converts the trajectory of the speed field coding to convert the system control method; the speed feedback IP control reduces the speed error, which reduces the external disturbance and parameter changes of the system.Wait for uncertain factors to ensure the performance of the system and improve the accuracy of contour processing.
