An electro-hydraulic servo control system research for CFETR blanket RH

•We discussed the conceptual design of CFETR blanket RH maintenance system.•The mathematical model of electro-hydraulic servo system was calculated.•A fuzzy adaptive PD controller was designed based on control theory and experience.•The co-simulation models of the system were established with AMESim/Simulink.•The fuzzy adaptive PD algorithm was designed as the core strategy of the system.
