Existence of solutions for the initial value problem. Uniqueness of solutions usually requires other conditions. Then the initial value problem. Differential inclusions can be used to understand and suitably interpret discontinuous ordinary differential equations, such as arise for Coulomb friction in mechanical systems and ideal switches in power electronics.

An important contribution has been made by A. Filippov, who studied regularizations of discontinuous equations. Further the technique of regularization was used by N. Krasovskii in the theory of differential games. Differential inclusions are also found at the foundation of non-smooth dynamical systems NSDS analysis,  which is used in the analog study of switching electrical circuits using idealized component equations for example using idealized, straight vertical lines for the sharply exponential forward and breakdown conduction regions of a diode characteristic  and in the study of certain non-smooth mechanical system such as stick-slip oscillations in systems with dry friction or the dynamics of impact phenomena.

Then practical stability properties of system 22 imply the corresponding h 0 , h -practical stability properties of Next we prove that system 18 is h 0 , h -strongly practically stable. Hence system 18 is h 0 , h -strongly practically stable.

Finally, we show that system 18 is h 0 , h -practically asymptotically stable. Now, let us suppose that 22 is practically asymptotically stable. Practical asymptotic stability of 22 means that. Suppose that the conditions of Theorem 21 are satisfied except that condition A 3 is replaced by. Then Q 0 , Q -practical stability properties of system 22 imply the corresponding h 0 , h -practical stability properties of the system Assume that 22 is Q 0 , Q -practically stable. Suppose that the h 0 , h -practical stability of 18 does not hold; then, arguing as in Theorem 16 , by A 2 , A 6 , we can show that.

Abstract We present a new comparison principle by introducing a notion of upper quasi-monotone nondecreasing and obtain the practical stability criteria for set valued differential equations in terms of two measures on time scales by using the vector Lyapunov function together with the new comparison principle. Introduction Stability theory in the sense of Lyapunov is now well known.

Remark 9 — The usual scalar subtraction occurs in the scalar coefficient at the beginning of the above expressions and the Hukuhara set difference occurs inside the brackets. Theorem 16 — Assume that H 1. Then one says that i. Other practical stability notions can be defined similarly. Theorem 21 — Assume that A 1. Theorem 22 — Suppose that the conditions of Theorem 21 are satisfied except that condition A 3 is replaced by A 6. Proof — Assume that 22 is Q 0 , Q -practically stable.
