Multi-motor distributed type control system under wireless network and multi-motor distributed type control method

Abstract

The invention discloses a multi-motor distributed type control system under a wireless network. An IPC (Industrial Personal Computer) system exchanges information with motor drive systems through the wireless network, each motor drive system comprises a DSP (Digital Signal Processor) module, an FPGA (Field Programmable Gate Array) module and an Ether CAT interface, and the Ether CAT interfaces assist in achieving information exchange between the IPC system and the motor drive systems and among the motor drive systems. The invention further discloses a multi-motor distributed type control method, namely, the motor drive systems are activated after the IPC system is started, and the FPGA modules and the DSP modules enable motors to achieve needed operation after analysis of control information. The motor drive systems exchange information of control commands, motor states and the like through the wireless network; as for a large complicated multi-motor system, the complexity of system construction can be effectively reduced, and the system stability precision and robustness can be improved; and the system structure is dynamically matched and optimized and the performance is controlled according to actual needs.
