For the artillery multi servo system positioning signal delayed and limited network capacity problems, design the embedded Ethernet positioning system by taking STM32F107VCT6 as the main control chip. For realizing artillery multi servo system high precision position control, use 6 artillery barrel networking, design high precision positioning artillery control system diagram. The system takes STM32F107VCT6 as positioning controller processer, and embeds advanced extended state observer fractional-order PID controller and uCOS-Ⅱ real-time operation system. Its Ethernet controller module adopts general hardware TCP/IP embedded Ethernet controller W5500 chip, use standard SPI serial interface, the network transmission rate is up to 100 Mbit/s. The simulate results show that the positioning controller runs stably, the Ethernet communication realizes real time. The Ethernet positioning system realizes precision positioning of multi artillery barrel. It reaches target effectiveness.
