This technical note investigates the robust stabilization problem for uncertain linear systems with discrete and distributed delays under saturated state feedback. Different from existing approaches, a distributed-delay-dependent polytopic approach is proposed in this note, saturation nonlinearity represented as convex combination of feedback auxiliary distributed-delay Then, by incorporating an appropriate augmented Lyapunov-Krasovskii (L-K) functional some integral inequalities, less...

The thermophysical properties of the nanofluids override physical conventional fluids due to high thermal conductivity nanoparticles. applications have varied use in era bio-engineering and sciences. Moreover, nanoparticles attributed significances human blood arteries. Therefore, present analysis manifests with free convection electrically conducting nanofluid embedding resistive forces such that magnetic field permeability medium. augmentation heat transfer is obtained because inclusion...

Irreversibility binary chemical reaction also deliberated. Nonlinear system reduced ODEs by suitable variables. Newton built shooting procedure adopted for numerical solution. Salient features velocity filed, Bejan number, entropy rate, concentration temperature are Numerical outcomes gradient mass transfer rates displayed...
This study addresses the consensus problem of multi‐agent systems by combining adaptive control protocol and event‐triggered communication strategy. Two protocols are designed to guarantee consensus. The strategy is utilised save reduce channel occupation. Each agent in system sends its state neighbours only at some irregular event instants determined an appropriately event‐triggering condition. At first, distributed condition employs own their latest instants. Later, another given such that...
In this paper, the problem of prescribed performance distributed output consensus for higher-order non-affine nonlinear multi-agent systems with unknown dead-zone input is investigated.

Based on Lyapunov stability theory dynamic surface control technique, a new algorithm proposed, which ensures cooperatively uniformly ultimately boundedness all signals in...
