Control method and system of multi-motor-driven synchronous control radar servo system

The embodiment of the invention provides a control method and system for a multi-motor-driven synchronous control radar servo system, and belongs to the field of multi-motor radar servo synchronous control. The control method comprises the following steps: acquiring the average speed of grouped driving motors and the position information of a load turntable; respectively calculating corresponding information by adopting a differential negative feedback method and a PID (Proportion Integration Differentiation) position method to obtain a first electric signal and a second electric signal; obtaining a third electric signal and a fourth electric signal by adopting a PID control method; adopting an anti-backlash method to obtain variable bias current corresponding to each group of driving motors; and generating a driving current for controlling the driving motor according to the third electric signal and the corresponding variable bias current. According to the method, a mode of superposing multiple control strat
