Research on Stability Control Method of Electro-Mechanical Actuator under the Influence of Lateral Force

This paper takes a multi-stage Electro-mechanical Actuator (EMA) as the research object, analyzes lateral force of EMA in vertical state, and overall mathematical model system. Firstly, permanent magnet synchronous motor module is built JMAG according to engineering requirements. Then, electrical control part mechanical transmission are established AMESim, ideal AMESim replaced with designed by construct EMA. The dynamic simulation ADAMS accurately simulate impact wind load on actual environment, this introduced into instead lead screw nut AMESim. improved active disturbance rejection (ADRC) used replace speed loop positional traditional three closed-loop control, whole system stability servo co-simulated. Finally, experiment method carried out LabVIEW. result shows that can effectively suppress under ensure stable operation In addition, co-simulation closer real working conditions than model. parameters be transplanted only minor adjustment meet
