Driving control method for novel slewing bearing test bed

The invention discloses a driving control method for a novel slewing bearing test bed. The method comprises the following steps of (1) obtaining the transfer function model of a slewing bearing control system by adopting a system identification method; (2) setting a step-change response trajectory expected by the system, iterating a parameter vector of an initial controller by adopting a nonlinear least square method, and keeping the parameter vector of the initial controller to be unchanged; (3) splitting the linear controller to obtain a parameter component and a structural component of the controller; (4) adding a coupling variable to the structural component of an initial linear PID controller to form a candidate controller, and subjecting the index of the coupling variable to iteration operation. According to the invention, based on the driving control method for the novel slewing bearing test bed, a traditional PID controller is subjected to nonlinear treatment, so that the accurate position control of
