【Abstract】 The gas-cooled micro-reactor based on the open-air Brayton cycle is a multi-input multi-output system with coupling among its control loops.To enhance control system performance, decoupling control methods for gas-cooled micro-reactor are investigated beyond traditional control systems. Based on the coupling analysis of the gas-cooled micro-reactor, sequential closed-loop decoupling control method and feedforward decoupling control method are proposed.Two decoupling control schemes are determined according to the proposed decoupling control methods, and corresponding decoupling control systems are designed.A decoupling control system model is constructed in Matlab & Simulink.The control system is validated through simulation tests.Simulation results demonstrate that compared to traditional control systems, the designed decoupling control systems reduce overshoots, shorten settling time, and exhibit superior control performance.The proposed method provides a reference decoupling control solution for gas-cooled micro-reactor.更多还原
