  • About author:FENG Wei (1984− ), Postgraduate, graduated from Nanjing University of Aeronautics and Astronautics, major in Electrical Engineering, senior engineer, employed in Shanghai Institute of Spaceflight Control Technology. He is mainly engaged in the research of electric servo system technology of launch vehicles.

Abstract: The 30 kW high-power electric servo system used in the solid booster of the Long March 6A (LM-6A) launch vehicle is introduced, and the function, composition of the system as well as its constituent equipments are detailed. To solve the problem of out-of-tolerance in the system dynamic characteristics, an advanced correction network algorithm architecture and double notch filter were designed. Experimental verification was conducted to prove that the dynamic characteristics requirement under multiple operating conditions could be met.
