| Abstract: |
| Since digital signal processor TMS 320 C32 processes high efficient computation ability and is supported with favorable development environment,a high-speed and high-precision digital controller for SH-2000 TH digital control system is designed based on TMS 320 C32 and FPGA.The performance and principle of TMS 320 C32 are described,as well as the HW and SW of SH 2000 TH.It controls motional process by means of PID and smoothes motional curve with algorithm of B-Spline interpolation.The control effect is close to continued systems. |
