基于FPGA的增量式PID控制器的研究与实现

The design and implementation of increasing PID controller based on FPGA

PID控制器的可靠性与实时性是使运动控制系统精确定位的重要环节,本文在分析数字PID控制算法的基础上,采用现场可编程逻辑门阵列(FPGA),应用自顶向下的设计方法,采用硬件设计语言VHDL语言进行编程,设计了增量式数字PID控制器.仿真结果表明,该设计方法是可行的,设计模块正确.

The reliability and real time performance of PID controller play a very important role in realizing the precise orientation of a motion control system. In this paper, VHDL is adopted to finish the top-down design of the increasing controller with FPGA based on PID control algorithm. The simulation results show the effectiveness of the method and the module is correct.
