Design and Realization of UAVActuator Controller Based on TMS 320F28069

The UAV actuator controller based on TMS320F28069 is designed and realized.The controller abandons the analog communication mode of the original actuator system instead of the RS485 interface serves to connect the flight control computer and the actuator system.According to the working mechanism of actuator system,the modular design of the hardware and software is realized based on the TMS 320F28069with high control precision,low power consumption and rich peripheral devices.The experiments indicate the controller designed has such advantages as great stability,high precision and reliability.The ambient interference can also be eliminated with the controller.
