In this article, the backstepping method is employed to stabilize a coupled wave-ODE system with internal anti-damping by means of decoupling them into stable cascaded system. At same time, existence kernels in transformation and inverse proved iterative method.
In this paper, sliding mode control approach is used to stabilize a 2×2 system of first-order linear hyperbolic PDEs subject boundary input disturbance. Disturbance rejection achieved, and with the designed controller, resulting closed-loop admits unique (mild) solution without chattering. Convergence chosen infinite-dimensional surface state trajectories takes place in finite time. Then on surface, exponentially stable decay rate depending spatially varying coefficients. A simulation...
Accurate Lithium-ion (Li-ion) battery internal temperature information enables high-fidelity monitoring and safe operation in management systems, thus prevents thermal faults that could cause catastrophic failures. This paper proposes an online estimation scheme for cylindrical Li-ion batteries based on a one-dimensional semilinear parabolic partial differential equation (PDE) model subject to in-domain output uncertainties, using measurements at the surface only. The state observer design...

This paper considers the modelling and control design of multi-agent systems in 3-D space. The communication graph agents is a mesh-grid 2-D cylindrical surface. Different from most existing literatures, where are modelled by ordinary differential equations (ODEs), we treat as continuum this paper. More specifically, model collective dynamics two reaction–advection–diffusion partial (PDEs). PDE states represent agent positions, equilibria correspond to possible formation manifolds. These...
Accurate online state-of-charge (SoC) estimation is a basic need and also fundamental challenge for battery applications. In order to achieve accurate SoC the lithium-ion batteries, we employ coupled thermal-electrochemical model. This system of an ordinary differential equation (ODE) partial (PDE) simpler than Doyle-Fuller-Newman (DFN) model, more single particle model (SPM) alone. Thus, it could serve as better fit full state observer design estimation. PDE backstepping approach utilized...

Semigroup linear operators is constructed in analyzing well-posedness stability target systems, mathematical induction used proving existence kernel functions. An example also presented, which illustrates performance controller. The rate estimate derived paper not necessarily...
Abstract This paper considers the stabilization of a heat‐ODE system cascaded at boundary point and an intermediate point. The stabilizing feedback control law is designed by backstepping method. Based on novel transformation, we prove that all kernel functions in forward inverse transformations are class C 2 . Moreover, effectiveness controller design shown with numerical simulation. Finally, show coherence between controllability assumption main theorem this known one for special case λ =0.
