摘要
在飞机集中除冰系统除冰液温度控制单元结构设计的基础上,分析了飞机除冰液加热温度控制系统的时变及时延特性。从理论上分析了迭代学习控制的稳定条件及对延迟干扰的鲁棒性,提出了基于迭代控制理论的除冰液温度控制策略,以克服系统的纯延迟给除冰液温度控制带来的不利影响。并利用系统的实际温升曲线模型对设计的控制策略进行了仿真研究,仿真结果验证了提出算法的有效性。
A temperature control system structure for aircraft deicing fluid was proposed based on the analysis of the state time-vary and time-delay characters of the system. A aircraft deicing fluid temperature control scheme was provided based on the theory of iteratire learning control （ILC） to alleviate the temperature fluctuation caused by the system state time-vary and time-delay. The valid of the proposed control algorithm was verified by the real system temperature raise model simulation.
