In the last few years, two new high-order accurate methods for unstructured grids have been developed, namely the spectral volume (SV) and the spectral difference (SD) method. Both methods are related to the well-known discontinuous Galerkin (DG) method, see for instance [1], in the sense that they also use piecewise continuous polynomials as solution approximation space. The development of the...

Abstract In this work, we apply the $$\overline{\partial }$$ ∂ ¯ -dressing method to study mixed Chen–Lee–Liu derivative nonlinear Schrödinger equation (CLL–NLS) with non-normalization boundary conditions. The spatial and time spectral problems associate CLL–NLS which...

In automatic flight control system or autopilots, multiple specifications criteria are needed to be satisfied concurrently, such as good holding (small static altitude holding error), fast response, smooth transition (less oscillation, overshoot). So how to design the MSS (Multiple Simultaneous Specification) controller effectively and practically is a very significant and challenging job. Liu ...

This letter discusses hybrid projective dislocated synchronization of Liu chaotic system with five uncertain parameters. Based on adaptive technique, the hybrid projective dislocated synchronization of Liu chaotic system is achieved by designing a novel nonlinear controller. Furthermore, the parameters identification is realized simultaneously. A sufficient condition is given and proved theoret...
