law of inertia
2.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.
3.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.
