Abstract：In a military application scene where multiple buck choppers independently drive independent loads, the output current of each buck chopper is required to have good consistency in the start and steady process. If it is not controlled, the consistency of the current will be severely affected by factors such as load differences and delays in starting communication. Based on the cooperative control of multi-agent systems, this paper designs a cooperative control strategy based on neighbor currents, and utilizes the neighbor current values to compensate the desired current value in real time to achieve the control goals of the system. Furthermore, the actual experiments on multi-buck chopper system are performed and industrial Ethernet EtherCAT for information exchange to meet the real-time requirements of the control system is introduced, thus verifying the effectiveness and excellent performance of the neighbor current cooperative control algorithm on solving the multi-chopper current cooperative problem.
