Based on the technology of personal computer and wireless transmission, a kind of self-propelled precise feeding machine control system for single dairy cow was designed．This kind of control system can realize the precise feeding of single dairy cow based on their physiological characteristics by using the technology of RFID and MCU．Using this system, the intelligent identification for single dairy cow and the information transmitted from personal computer to MCU by air were realized. The dual-mode moving and accurate feeding was achieved. The experimental results showed that the best rate of the precise feeding machine was 0.6m/s. The response time of the machine was 0.4s. The control system can identify 96% of the single dairy cow correctly. The feeding error was controlled at below 2%.
