Abstract
The present invention discloses a positioning control apparatus which receives a moving command and a feedback signal outputted from a controlled device, and controls the controlled device for moving and positioning. The positioning control apparatus includes a first control loop, a second control loop and an arbitration module with a dead point default value, wherein the first control loop is used to control the controlled device moving in response to the error of the moving command and the feedback signal, on the other hand, the second control loop is used to control the controlled device positioning. Furthermore, the arbitration module compares the default value of dead point with the moving command so as to enable either the first control loop or the second control loop.
