A set of aircraft stepper motor control system based on RVDT position feedback is designed. The system mainly includes sensor interface, hardware interface, software interface and data interface. The sensor interface uses a two-phase hybrid stepping motor as the servo information source, and uses the RVDT position sensor as the position feedback. The hardware interface utilizes the inverse time protection double H grid motion rate drive circuit and high precision rectification circuit to achieve high safety motor drive and high precision position acquisition. The software interface uses the subdivision control strategy to achieve accurate control. The data interface adopts validity verification, combined with the integrated processing of instruction data, state data and BIT data, achieving high reliability control. The experimental results show that the motor control strategy developed in this paper has good additive performance, high control precision, safe and reliable system, and has good practical value.
