Description
Summary:•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. Based on the technical design requirements of China Fusion Engineering Test Reactor (CFETR) blanket remote handling (RH) maintenance, this paper focus on the control method of achieving high synchronization accuracy of electro-hydraulic servo system. Based on fuzzy control theory and practical experience, a fuzzy adaptive proportional-derivative (PD) controller was designed. Then a more precise co-simulation model was established with AMESim/Simulink. Through the analysis of simulation results, a fuzzy adaptive PD control algorithm was designed as the core strategy of electro-hydraulic servo control system.
