Heat pipe adaptive thermal regulation system based on two-phase flow regime prediction

Abstract

The present application relates to the general control or regulation system technical field, disclose a kind of heat pipe adaptive heat regulation system based on two-phase flow state prediction, including feature acquisition unit, flow state prediction unit, trajectory analysis unit and control decision unit, system obtains the temperature vibration coupling signal of controlled heat circulation loop and is converted into multidimensional feature vector, according to mapping operator prediction working medium flow state phase transition trend, trajectory analysis unit generates evolution trajectory by phase space reconstruction, and the curvature of the trajectory in sliding window is calculated, control decision unit adjusts control topology according to trajectory curvature, curvature is below threshold, output linear regulation instruction, curvature is not below threshold, switch to damping dissipation mode, the present application identifies instability precursor through trajectory curvature monitoring, eliminates the control blind area caused by phase transition lag, inhibits the nonlinear oscillation generated by thermal load fluctuation, ensures that heat regulation loop runs smoothly and improves system stability margin.
