The mechanism is composed of two ball screws, U-type linear rails, linear bearings and flexible couplings. The permanent magnetic direct current motors are used as actuators. The rotary encoder is used to measure the angular position of the DC motor. The digital controller is implemented on the personal computer and a motion control card (EPCIO-6000). The objective of this thesis is to realize precise positioning control using a real-time motion control system on an X-Y table.
