| Abstract: | Movement framework control system based on PXI bus consists of position control board, interface circuit, drive unit, engine, and execution department. The IPC linked with PXI bus system through MXI-3 multi-system expansion interface. Its movement control board includes DSP, four-line D/A transducer, FPGA and so on. The DSP was used to realize the PID modification of position and speed control. FPGA realized the logic function of module interface. The system software process controlled the system through setting control object and operation parameter, collecting and sending operation status information. |
