This paper investigates the mean-square stabilization problem for discrete-time networked control systems (NCSs). Different from most previous studies, we assume transmission delay and data packet dropout may occur simultaneously. The such NCSs remains challenging because of fundamental difficulty in stochastic control. contributions this are threefold. First, present two different necessary sufficient stabilizing conditions terms unique positive solution to delay-dependent algebraic Riccati...
The five-phase open-end winding inverter topology has a low-impedance zero-sequence current path when single dc supply is used. As result of this, any source common-mode voltage in the circuit can lead to an uncontrolled low-frequency current. This issue for permanent magnet machine systems as they possess components back electromotive force, which will couple with generated produce undesired torque pulsations. One possible solution reducing these pulsations use proportional-integral...
In this paper, we mainly study an integrated networked control system (NCS) operating over multi-path routing networks, where the delivered signal in each path experiences both transmission delay and packet loss. These imperfections significantly compromise performance may even cause instability. For such a system, derive, for first time, necessary sufficient stabilization condition utilizing delay-dependent algebraic Riccati equation (DDARE). Different from many previous works, one...

In this article, we study sampled-data networked control systems (NCSs) that operate over communication networks with multipath channels. Due to limited bandwidth power, the delivery of observed state signals from sensor controller may suffer packet loss possibility, which leads intermittent observation. An unreliable routing network is responsible for transmission actuator, subject random delays. These problems lead degradation in system performance, even cause instability. By utilizing an...

Experimental measurements show that SWG with minimum feature size of ∼210 nm has peak coupling efficiency -7.0...
ABSTRACT This article aims to achieve global adaptive control of nonstrict‐feedback non‐linear systems with unknown functions and time‐varying delay. Unlike traditional methods, this approach introduces switching at each step the backstepping design, in addition utilizing neural networks (NNs) approximate functions, resulting globally bounded outcomes. By employing appropriate Lyapunov‐Krasovskii (L‐K) functionals, negative effects delays are effectively compensated. The proposed scheme...
