In this paper we study nonlinear periodic systems driven by the ordinary p-Laplacian with a nonsmooth potential. We prove an existence theorem using a nonsmooth variant of the reduction method. We also prove two multiplicity results. The first is for scalar problems and uses the nonsmooth second deformation lemma. The second is for systems and it is based on the nonsmooth local linking theorem. 相似文献

In this paper we present an extension of Moreau’s sweeping process for higher order systems. The dynamical framework is carefully
introduced, qualitative, dissipativity, stability, existence, regularity and uniqueness results are given. The time-discretization
of these nonsmooth systems with a time-stepping algorithm is also presented. This differential inclusion can be seen as a
mathematical formulation of complementarity dynamical systems with arbitrary dimension and arbitrary relative degree between
the complementary-slackness variables. Applications of such high-order sweeping processes can be found in dynamic optimization
under state constraints and electrical circuits with ideal diodes. 相似文献

The paper deals with the analysis of the behavior of a nonsmooth three-dimensional vector field around a typal singularity. We focus on a class of generic one-parameter families \({Z_{\lambda}}\) of Filippov systems and address the persistence problem for the asymptotic stability when the parameter varies near the bifurcation value \({\lambda = 0}\). 相似文献

In this paper we study the existence of nontrivial solutions for a class of gradient-type systems on strip-like domains where the nonlinear term is not necessarily continuously differentiable. The proof of the main result is based on a nonsmooth version of the Mountain Pass Theorem which involves the Cerami compactness condition and on the Principle of Symmetric Criticality for locally Lipschitz functions. 相似文献

In this paper solvability and Lipschitzian stability properties for a special class of nonsmooth parametric generalized systems
defined in Banach are studied via a variational analysis approach. Verifiable sufficient conditions for such properties to
hold under scalar quasidifferentiability assumptions are formulated by combining *-difference and Demyanov difference of convex
compact subsets of the dual space with classic quasidifferential calculus constructions. Applications to the formulation of
sufficient conditions for metric regularity/open covering of nonsmooth maps, along with their employment in deriving optimality
conditions for quasidifferentiable extremum problems, as well as an application to the study of semicontinuity of the optimal
value function in parametric optimization are discussed.

This paper deals with linear control systems of a special form. The main goal of the paper is to find the exact analytic solution of the time-optimal control problem for an arbitrary linear control system with constant coefficients using the analytic solution of this problem for the canonical system. For this aim, we construct a certain nonsmooth mapping between the 0-controllability sets of the given systems. In other words, by means of this mapping, we investigate the equivalence of the systems with the same qualitative behavior in a neighborhood of the stationary point. 相似文献

The problem of the decentralized stabilization of a class of large-scale nonlinear and linear systems including time-varying delays in the interconnections is considered. By combining the Razumikhin-type theorem with the Lyapunov stability theory, we propose a class of decentralized state feedback controllers which can guarantee always some type of stability of large-scale time-delay systems. In this paper, we assume that the time-varying delays are continuous and bounded nonnegative functions. Furthermore, since the proposed decentralized state feedback controllers are independent of the delays, the results obtained in this paper are applicable to systems without exact knowledge of the delays, i.e., systems with perturbed delays. Finally, a numerical example is given to demonstrate the validity of the results. 相似文献

Necessary and Sufficient Condition for Robust Stability and Stabilizability of Continuous-Time Linear Systems with Markovian Jumps 总被引:2,自引:0,他引:2
In this paper, we investigate the quadratic stability and quadratic stabilizability of the class of continuous-time linear systems with Markovian jumps and norm-bound uncertainties in the parameters. Under some appropriate assumptions, a necessary and sufficient condition is established for mean-square quadratic stability and mean-square quadratic stabilizability of this class of systems. The quadratic guaranteed cost control problem is also addressed via a LMI optimization problem. 相似文献
