On the generation of multipartite entangled states in Josephson architectures [PDF]

, 2006
We propose and analyze a scheme for the generation of multipartite entangled states in a system of inductively coupled Josephson flux qubits. The qubits have fixed eigenfrequencies during the whole process in order to minimize decoherence effects and ...

Improved composite adaptive fault‐tolerant control for dynamic positioning vehicle subject to the dead‐zone nonlinearity

IET Control Theory & Applications, 2021
In order to tackle the marine practical constraints, for example the actuator faults, the dead‐zone input, an improved composite adaptive neural control algorithm is proposed for dynamic positioning vehicles in presence of the unknown external ...

State prediction based control schemes for nonlinear systems with input delay and external disturbance

IET Control Theory & Applications, 2021
In this paper, a control scheme based on state prediction is proposed for a class of nonlinear systems subject to input delay and external disturbance. Firstly, as for constant input delay, an improved control scheme that combining state prediction with ...

Communication constrained robust guidance strategy using quantized artificial time delay based control with input saturation

IET Control Theory & Applications, 2021
This work proposes the use of a logarithmic quantizer to minimize the computational load on the onboard processor of missiles. The quantizer output discretizes the continuous guidance command to a finite set of predefined discrete levels.
