摘要
采用自顶向下的设计思想和自下而上的实现流程,基于Verilog HDL语言实现PID控制算法,设计出一种基于FPGA的大型望远镜伺服控制器,从而实现望远镜速度环和位置环的高精度控制功能。
In order to satisfy the requirements of integration and modularization of servo control system when detec- ting spatial target and doing astronomical research, a servo controller of large telescope is designed based on FPGA, which realizes the function of high-precision control in speed loop and position loop. Based on Verilog HDL, it imple- ments PID control algorithm, encoder signal processing, PWM waveform generation, LCD display and communication with PC etc, by using options of combining the top-down thinking and the bottom-up method. The controller which has characteristics such as high integration, small size, good stability implements a SOC solution to some extent.
