inertia time
4.Abstract: This paper considers the stabilization problem of the dynamic nonholonomic systems with unknown constant inertia parameters.New periodic time-varying adaptive stabilizing laws are presented for a class of the systems.Unlike the feedback laws in other papers,they are not high-gain ones.The stabilization problem of the general uncertain dynamic nonholonomic system is also addressed,and the existence of the periodic time-varying adaptive stabilizing law is proved.Simulation results of an exapmle show that the approach is effective.
6.In this paper, a new control algorithm named ADRC is given for main stream temperaturecontrol system with the properties of high inertia and strong delay and time-variation andmulti-disturbances.
7.The mathematical model of principal axis moment of inertia of the ball rotor with time when the quasi-fluid is flowing out was established by using the parallel cross-section method,then the expression of nutation moment was obtained by substituting the mathematical model into the Euler equation,which provide the theoretical law for realizing delay arming function of fuze.
9.Analysing the reasons of floating for objects in the reference system of non-inertia, the paper discusses the relationship between the depth and time, as well as the floating object and its acceleration, these relationships will provide convinient to explain some questions of the hydrostatics.
