| Summary: | 碩士 === 中原大學 === 機械工程學系 === 85 === In this dissertation, the PD and PID control theory is used to design the digital controller and also take the digital signal processor (DSP) which has high-speed calculating ability as the major part for calculating. Then applied them to perform the positioning control system. First, we simulate the system response by computer, then applied the results from simulation to the real system. The structure design of the positioning control system is using the digital signal processing on the control board to go with the 8255 IC for the output of pulse wave to the servo motor driver. The AC servo motor drives ball screw and gets the position pulse signal of the system from the linear scale to feed back to the encoder interface of the control board. Then we can transmit the data back to the digital signal processor and also applies the control theory program that is loaded to the digital signal processor at the beginning to calculate the output of the next control command. During the operation stage, all signals are digitized, so it can say to be a full digitized control system. Finally, in this dissertation we base on the single axis positioning system for simulation and experiments also the two axes cartesian coordinate XY table for experiments.
