Research on hardware-in-the-loop simulation technology for space pumped single-phase fluid loop
摘要
Abstract
In view of the high cost and high risks in conducting full-scale physical experimental validation for space pumped single-phase fluid loop,as well as the challendges in the equivalent simulation of space radiation and heat dissipation behavior in atmospheric environment,a hardware-in-the-loop simulation(HILS)test platform architecture based on CAN bus was proposed.By utilizing a space thermal model to replace some physical entities and integrating ground-based method for equivalent validation of single-phase fluid loop radiator in ambient pressure,the rapid and reliable online validation of the dynamic characteristics of the control system for the space pumped single-phase fluid loop was achieved.The results show that the temperature control accuracy of the system can generally reach±0.5℃under three working conditions.There is little difference in the temperature control performance between conventional PID and neuron PID.The impact of short-term transient high heat flux on the temperature of the control point of main circuit does not exceed 1℃.The proposed research may provide a new technical approach for the development and validation of space pumped single-phase fluid loop control systems.关键词
