| Abstract: | A servo controller of high-precision large telescope is designed based on high speed MCU C8051F120 and CPLD.Closed loop control algorithm,communication with PC,and LCD display control are implemented in MCU.Incremental encoder counter,motor driver waveforms,and I/O interface are implemented in CPLD.The controller can run alone or work with PC.It has characteristics such as good real-time performacne,high anti-disturbance ability,low cost and easy adjustment. |
