A dimension reducing method for solving Lurie( )'s problem is studied, it is proved that the absolute stability of a nonlinear control system is equivalent to that of another system with a lower dimension when the feedback vector c belongs to the invariant subspace of a definite linear transform. It is also pointed out that the Aizerman conjecture is true if c belongs to one or two dimensional invariant subspace of the linear transform. Some applications and examples are given.

A mathematical model for real time simulation of twin spool turbojet engine has been established,which comprises a linearized compressor characteristics model,simplified turbine characteristics and the dimension reducing method of non linear equation set.Under the identical regime and inlet flow conditions,the performance of the twin spool turbojet engine was simulated respectively by real time model and non real time model.The results of the simulations were compared with test data.Favorable results of the comparison give the validation of the fundamental hypothesis of this study.This model makes a very good compromise between computation speed and accuracy,and has good convergence.

建立了能够实时模拟双轴涡喷发动机性能的数学模型。该实时模型包括:线性化的压气机特性模型、简化的涡轮特性以及非线性方程组的降维处理。在相同工况及进气条件下,分别用非实时模型和实时模型对某型双轴加力式涡喷发动机性能进行了模拟,并与试验结果进行了对比。结果表明,该模型很好地解决了提高运算速度与保证计算精度之间的矛盾,并且具有较高的收敛性。
