Electric drive type rocket launching pad supporting arm control system

The invention belongs to the technical field of rocket launching, and discloses an electric drive type rocket launching pad supporting arm control system which comprises a servo control system, a supporting arm structure and a multi-motor linkage PID control strategy module. A PLC (Programmable Logic Controller) in the servo control system issues an instruction to control a servo driver to drive a servo motor; the supporting arm control system has a local control mode and a remote control mode. The servo driver is controlled by the programmable controller to drive the servo motor, the nut-screw transmission mechanism is driven to act, and the perpendicularity of the rocket body is adjusted through lifting of the supporting arm. The electrical system monitors the displacement and stress state of the supporting arm in real time through measurement data of the displacement sensor and the force sensor, and uploads operation data of the supporting arm to a rocket launching pad control subsystem through an Ethernet
