Research on the control system of antenna panel lifting platform with multi-screw drive

This paper designs a control system of an antenna panel lifting platform driven in parallel by four sets of screw elevators(SEs), analyzes the working principle of the lifting platform control system, establishes the dynamic model of the lifting platform, analyzes and proposes the equivalent model of the asynchronous error of the parallel screw feed system of the SE, conducts simulation research for the established control system model, and on this basis, simulates and analyzes the influence of installation errors of the four sets of SEs, inconsistent motor resistance parameters, and inconsistent motor inductance parameters on synchronous control.
