In this paper, we mainly study error bounds for a single convex inequality and semi-infinite constraint systems, give characterizations of stability via directional derivatives. For inequality, it is proved that the local under small perturbations essentially equivalent to non-zero minimum derivative at reference point over unit sphere, global be strictly positive infimum derivatives, all point...

UAVs formation is a complex nonlinear system. Although quadrotor has many advantages, its dynamics model nonlinear, coupled, and under driven. For model-based controller design, physical constraints, uncertainties external disturbances significantly deteriorate control performance. Therefore, multi-constraints MPC strategy based on error proposed for the formation. Firstly, 3D established by us...

A popular combination in modern coding system is the convolutional encoder and the Viterbi decoder [5]. With a proper design, they can jointly provide an acceptable performance with feasible decoding complexity. In such a combination, a tradeoff on the error performance and the decoding complexity resides on the choice of the code constraint length. Specifically, the probability of Viterbi deco...

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...

We consider Constraint Satisfaction Problems in which constraints can be initially incomplete, where it is unknown whether certain tuples satisfy the constraint or not. We assume that we can determine such an unknown tuple, i.e., find out whether this tuple is in the constraint or not, but doing so incurs a known cost, which may vary between tuples. We also assume that we know the probability o...
