In this paper we investigate the interaction of disturbance decoupling requirement with the robustness of closed loop stability in the sense of normalized coprime factor perturbations. The disturbance decoupling and the robust stabilization requirements are expressed in terms of the subspace valued functions associated to plant and controller and an upper bound on robustness of stability impose...

Abstract: The current control for interior permanent magnet machines is more complicate than surface permanent magnet machine because of its torque characteristic depending on the reluctance. For high performance torque control, it requires state decoupling between the d-current and q-current dynamics. However the variation of the inductances, which couples the state dynamics of the currents, m...

The input–output block decoupling problem by state feedback is studied for linear time-varying singular systems. First, an algorithm, the regularization algorithm, is developed such that the system can be made by state feedback to have a unique impulse-free solution. Second, another algorithm, the block decoupling algorithm, is proposed, which provides sufficient conditions for the solvability ...

We report a high fidelity optical memory in which dynamical decoupling is used to extend the storage time. This is demonstrated in a rare-earth doped crystal in which optical coherences were transferred to nuclear spin coherences and then protected against environmental noise by dynamical decoupling, leading to storage times of up to 4.2 ms. An interference experiment shows that relative phases...

The purpose of this paper is to study the roles of the distributor in the supply chain and to explore its positive contributions. We find that the distributor should act as a push and pull boundary (also called decoupling point) of the supply chain. The definition of decoupling point is needed to be enhanced when the concept of the decoupling point is applied to an industry, like the electronic...

Decoupling capacitors (decap) are often used to filter out noise in the power distribution system (PDS). Decaps acts as a local source of energy for a short period. With the scaling of CMOS technologies the power supply voltage is lowered, clock frequency has gone up, and more functionality is integrated on-chip resulting in higher simultaneous switching noise (SSN). As a result signal integrit...

In this paper we consider disturbance decoupling problems for switched linear systems. We will provide necessary and sufficient conditions for three different versions of disturbance decoupling, which differ based on which signals are considered to be the disturbance. In the first version the continuous exogenous input is considered as the disturbance, in the second the switching signal and in ...

A decoupling method based on radical basis function neural network (RBFNN) for a novel threedimensional force flexible tactile sensor is presented in this paper. A numerical model of the tactile sensor is built through finite element analysis, which simulates the mapping between three-dimensional force applied on top surface of the sensor and deformation of the sensor. Furthermore, the RBFNN is...

This paper examines the performance potential of decoupled computer architectures on real-world codes, and includes the rst performance bounds calculations to be published for the highly-decoupled ACRI-1 computer architecture. It also constitutes the rst published work to report on the eeectiveness of a decoupling Fortran90 compiler. Decoupling is an architectural optimisation which ooers very ...

Several continuous-time formulations in the literature address the most demanding problem of scheduling in multipurpose batch plants. These formulations can be broadly classified into two types based on the assignment binary variables. They are (i) Formulations with decoupling and (ii) ones without decoupling. The former rely on the postulation that decoupling the tasks from units reduces the n...
