Explicite controller Explicite solution of stabilizing problem with time delay is calculated. It is formulated as a robust stabilizing problem of multiplicative uncertainties without approximations. Explicite H_*, controller with infinite degree is obtained analytically by resulting in Nevannlina-Pick interpolation problem.Application to aircraft dynamics The controller stabilizing roll dynamics of aircraft is designed. It is shown that the stability margin of natural frequency of Dutch roll mode is small. And stability margin of delay time is estimated by small gain theorem and Nyquist method. Because small gain theorem is conservative, estimated margin by Nyquist is larger than by small gain theorem. Numerical simulations in time domain indicate that the responses have good characteristics if the miss matching of delay time is in the margin guaranteed by small gain theorem.

计算了具有时滞的稳定问题的显式解。它被表述为一个不带近似的乘法不确定性的鲁棒稳定问题。通过对Nevannlina-Pick插值问题的分析，得到了具有无限次的显式H_*控制器。在飞机动力学中的应用设计了稳定飞机横摇动力学的控制器。结果表明，荷兰横摇模式的固有频率稳定裕度较小。利用小增益定理和奈奎斯特方法估计了时延的稳定裕度。由于小增益定理是保守的，Nyquist的估计边际比小增益定理的估计边际大。时域数值模拟结果表明，在小增益定理保证的范围内，延迟时间的不匹配具有良好的响应特性。
