Abstract

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.
