摘要
针对一维固定边界复合介质发汗冷却系统的自适应控制问题 ;给出了一个根据实际观测 .基于对气动加热面边界热流密度的估算 ,由热平衡方程及热阻滞函数的特征确定控制输入的自校正控制方法 .理论和数据试验显示 ,对时变的热流及未知的热阻滞函数 ,此方法可以取得很好的控制效果 .
A self-tuning cointrol scheme is presented based on observation temperature for one-dimensional multi-layer fixed boundary transpiration cooling system. The boundary heat flux is estimated by two points observation and heat equilibrium; the adaptive control input is obtained by heat equilibrium equaiton and the characteristic of heat blockage function. The numerical simulation shows that the approach is feasible and effective for time-varying heat flux and unknown blockage function.
