On the Criterion for the Absolute Stability of the Control System

摘要: 本文:1.给出非线性控制系统第二标准型^[2]平凡解绝对稳定性准则,特别地给出了飞机纵向运动方程平凡解绝对稳定性准则,文[8][9]中关于飞机纵向运动方程的结果是本文推论2.2的特例;2.给出非线性控制系统第一标准型^[2]平凡解在通常情况和一种临界情况下绝对稳定准则;3.给出了Lure型直接控制系统一般型平凡解绝对稳定若干准则,全文结果均根据系统本身的参数,具体构造函数,给出显式判据.

Abstract: In this paper, firstly we give the criterion for the absolute stability of the second canonical form for the control system, including.the equation of the longitudinal motions of a plane as a particular example. The corresponding result in [8],[9] is a particular example given in this paper. Secondly, we give the criteria for the absolute stability of the first canonical form in the usual case and in the critical case. Finally, we give some criteria for the absolute stability of the general form for the direct control system.All the results in this paper merely depend upon the relations between the parameters of the system itself to give an explicit algebraic discriminant.
