By employing a generalized Riccati transformation and integral averaging technique, two Philos-type criteria are obtained which ensure that every solution of class third-order neutral differential equations with distributed deviating arguments is either oscillatory or converges to zero.These results extend improve related reported in the literature.Two illustrative examples provided.
The Vienna-type rectifier is widely used in many applications due to the merits of controllable dc-link voltage, realizable three-level operation, and compact size. However, input currents near zero-crossing point are distorted inevitably its special topology. Based on analysis causes current distortion, a lagging reactive power compensation method proposed. d-q-axis models developed, two finite-time controllers designed enhance interference suppression performance. asymptotic convergence...
This paper is concerned with the asymptotic properties of solutions to a third-order nonlinear neutral delay differential equation distributed deviating arguments. Several new theorems are obtained which ensure that every solution this either oscillatory or tends zero. Two illustrative examples included.
This paper is concerned with the existence results of nonlocal problems for a class fractional impulsive integrodifferential equations in Banach spaces. We define piecewise continuous control function to obtain on controllability corresponding systems. The are obtained by means fixed point methods. An example illustrate applications our main given.
Parallel three-level rectifiers are widely employed to increase the power rating and efficiency of high-power converters. However, zero-sequence circulating current (ZSCC) will occur due voltage difference between parallel-operated converters, which can lead distortion system loss. Therefore, an improved finite-time controller is proposed for mitigating ZSCC in this article. A generalized model ZSCCs a parallel rectifiers' developed designing controller. The stability against parameter...

The objective of this paper is to study oscillation a forced second-order neutral differential equation. By using the generalized Riccati substitution and integral technique, new sufficient condition obtained which insures that all solutions studied equation are oscillatory. An illustrative example included.
This paper is concerned with the problem of finite-time stability (FTS) a class switched systems delayed arguments and nonlinear perturbations which are related not only current state but also time t.Novel Lyapunov-Krasovskii functions introduced, new criterion derived by employing average dwell (ADT) approach linear matrix inequality technique.An example given to illustrate effectiveness proposed method.
The paper considers state estimation for switched systems, in which both nonlinear disturbances and impulsive effects are contained. By exploiting Bihari's inequality technique, some stability criteria established by designing average dwell time (ADT) switching law, include existing results as special cases. A representative example is also specified to testify the superiority of approach.
