چکیده
This paper develops a novel control synthesis method for safe stabilization of control-affine systems as Differential Complementarity Problem (DCP). Our design uses Lyapunov function (CLF) and barrier (CBF) to define complementarity constraints in the DCP formulation certify stability safety, respectively. The CLF-CBF-DCP controller imposes soft constraint, which is automatically relaxed when safety constraint active, without need parameter tuning or optimization. We study closed-loop system behavior with identify conditions on existence local equilibria. Although certain cases yields undesirable equilibria, those can be confined small subset set boundary by proper choice parameters. Then, our avoid equilibria that CLF-CBF quadratic programming techniques encounter.

The Fold Complementarity Problem and the Order Complementarity Problem
We consider the Fold Complementarity Problem, which is one of the recent subjects in complementarity theory. It is a mathematical model used in economics in the study of distributive problems (cf. [25], [5]). A particular case is the k-Fold Complementarity Problem, studied using a variant of the notion of Z-function by A. Villar [25]. In this way, Villar obtained the solution of this problem as...

This paper is devoted to consider the notions of complementary problem (CP) and set-valued complementary problem (SVCP). The set-valued complementary problem is compared with the classical single-valued complementary problem. Also, the solution set of the set-valued complementary problem is characterized. Our results illustrated by some examples. This paper is devoted to co...
متن کاملAutomatic Verification of Stability and Safety for Delay Differential Equations
Delay differential equations (DDEs) arise naturally as models of, e.g., networked control systems, where the communication delay in the feedback loop cannot always be ignored. Such delays can prompt oscillations and may cause deterioration of control performance, invalidating both stability and safety properties. Nevertheless, state-exploratory automatic verification methods have until now conc...
متن کاملNumerical method for solving optimal control problem of the linear differential systems with inequality constraints
In this paper, an efficient method for solving optimal control problems of the linear differential systems with inequality constraint is proposed. By using new adjustment of hat basis functions and their operational matrices of integration, optimal control problem is reduced to an optimization problem. Also, the error analysis of the proposed method is nvestigated and it is proved that the orde...
