摘　　要：为了满足控制器能通用于各种超高速、高可靠性应用场合的需求,设计了一种基于FPGA的超高速工业控制器,其核心控制单元是EP3C16系列芯片。该控制器硬件功能单元主要包括A/D转换单元,D/A转换单元,开关量输入/输出调理单元和总线通信单元,抗干扰设计保证了FPGA与各硬件单元的隔离与电源独立。在FPGA内部用Verilog HDL语言实现了控制器在上位机的监控下完成模拟量、开关量的高速采集与控制,并以低于0.3 ms的控制周期实现8个双闭环PID或单闭环PID自动控制。最后通过实验,验证了该控制器高速理想的控制效果。To satisfy the need of universal controllers for super-fast, high-reliability applications, an ultra high speed industrial controller based on EP3C16 series FPGA was designed. The controller hardware function units include A/D conversion unit, D/A conversion unit, digital input/output conditioning units and bus communication unit. Anti-interference design ensures independent power supply and isolation between FPGA and the hardware function units. The controller achieves high-speed acquisition and con- trol of analog and digital signals under the supervision of host computer, and achieves PID controls of eight double or single closedloops in a control cycle as low as 0.3 ms, which is designed in Verilog HDL. The experiment proves the high speed and ideal control effects of the controller.
