中文摘要

      航天器地面试验瞬变热流控制具有耦合变量多,参数不确定、控制要求复杂、微分效应大等特点,本文采用控制矩阵非对角元强迫滞后一步的多变量全系数自适应控制方法,结合采用广义对象技术,充分利用成熟的二阶单变量全系数自适应控制方法在性能鲁棒性设计上的经验,通过数学仿真、原理性实验、模拟星实验等技术途径确定了控制系统的参数,圆满地解决了航天器地面试验瞬变热流控制,已成功应用在某卫星整星地面试验瞬变热流控制中.

英文摘要

      Directed against the difficulties brought by many coupled variables，uncertain parameters and complicate demands of the control of spacecraft instantaneous thermal current ground experiment，we adopted the compled-one-step-delay multivariable adaptive control method combined with generalized plant technique.At the same time，we also made full use of the mature design experiences of two order single variable all coefficients adaptive control method，especially in the design aspect of performance robustness. We determined the parameters of the control system through mathematical simulation，principle experiment and analogue satellite experiment and fimally solved the difficulties in the control system design. The result of this paper has been already used in instantaneous thermal currmal ground experiment of a satellite.
