Dual time scale systems such as /spl Delta/-/spl Sigma/ modulators, switching power converters, and phase-locked loops often take an excessive amount of computation time to simulate when using a circuit simulator and do not have sufficient accuracy when simulated with more efficient methods.

Dual-Time Scale Photoinduced Electron Transfer from PbS Quantum Dots to a Molecular Acceptor
Journal of the American Chemical Society, 2012A combination of picosecond and microsecond transient absorption dynamics reveals the involvement of two mechanisms by which 1,4-benzoquinone (BQ) induces the decay of the excited state of PbS quantum dots (QDs): (i) electron transfer to BQ molecules adsorbed to the surfaces of PbS QDs and (ii) collisionally gated electron transfer to freely diffusing ...

The rolling optimization strategy of CCHP system based on the electric-thermal dual time-scale
2019 Chinese Automation Congress (CAC), 2019The combined cooling, heating and power (CCHP) system, as one of the important development direction of distributed energy, has a excellent application prospect and development significance. Furthermore, the CCHP system itself is a complicated system with many kinds of energies coupling.

Dual-time scale crystal plasticity FE model for cyclic deformation of Ti alloys
Journal of Computer-Aided Materials Design, 2007A dual-time scale finite element model is developed in this paper for simulating cyclic deformation in a Titanium alloy Ti-6242. The material is characterized by crystal plasticity constitutive relations. Modeling cyclic deformation using conventional time integration algorithms in a single time scale can be prohibitive for crystal plasticity ...

Two-layer structure predictive control of target tracking mode for dual time-scale system
2020 Chinese Automation Congress (CAC), 2020In the dual time-scale system, the time for the fast and slow model to reach steady-state values is inconsistent. Based on the "point" model strategy of integral variables, this paper compares and analyzes the slow model variables with the integral variables and designs a two-layer structure predictive controller for the dual time-scale system under ...

Dual Time-Scale Control of Flexible Manipulator Based on Double-Power Sliding Mode and LQR
2020 39th Chinese Control Conference (CCC), 2020Trajectory tracking and vibration suppression of flexible manipulators are addressed in this paper. A control method combining double-power sliding mode and linear quadratic regulation is proposed. Firstly, the hypothetical modal method is used to describe the vibration mode of the flexible manipulator, and then the Lagrange dynamic equation is used to

Computing Dual Time-scale Dynamic User Equilibria
Traffic assignment is a set of criteria through which the demand for mobility is distributed over the links of a transport network. Over the last 30 years, Dynamic Traffic Assignment (DTA) models have been developed to support time-dependent analyses in nascent fields that need to take into account the temporal distribution of demand and supply.Terry L.
