Zusammenfassung:The invention provides a multi-motor synchronous control system and method based on a reflective memory network, and belongs to the technical field of power electronics and multi-motor transmission. The system comprises four sets of synchronous controllers which are consistent in structure, and each set of synchronous controller is composed of a CPU board based on a VME bus, a reflective memory board and a DSP board; and each set of synchronous controller controls a synchronous motor, and each synchronous motor is connected with a frequency converter and a signal acquisition board of the synchronous motor. The method comprises the following steps that: firstly, the signal acquisition board of each synchronous controller acquires each piece of information and stores the information in the CPU board; then, a CPU board of the main synchronous controller calculates a torque current main given value istgd1 and realizes rotation of a main motor; and the CPU transmits a torque current main given value istgd1 to othe
