The penetration of lithium-ion batteries (LIBs) in transport, energy, and communication systems is increasing rapidly. A meticulous but simplified LIB model for non-uniform internal state monitoring online control sought practice. Based on the pseudo-two-dimensional (P2D) model, a electro-chemical LIBs proposed. Specifically, rigorous reaction rates inside battery derived. Sub-models that captu...

The conventional model predictive control (MPC) is an attractive scheme for the regulation of multiphase electric drives, since it easily exploits their inherent advantages. However, as number phases increases, MPC’s complexity increases exponentially, posing a high computational burden. Additionally, MPC still presents other issues related to weighting factor design in cost function. According...

For sensorless control of surface-mounted permanent magnet synchronous machines (SPMSMs), the major issue is in zero- and low-speed ranges. Since back-electromotive force (EMF) proportional to speed, back-EMF based methods fail at zero low speed. A solution considering starting process speed presented. simplified fundamental model-based method proposed. Based on model, measured stator currents ...

In this paper, we compare three different control methodologies for helicopter autopilot design: linear robust multi-variable control, fuzzy logic control with evolutionary tuning, and nonlinear tracking control. The control design is based on nonlinear dynamic equations with a simplified thrust-torque generation model valid for hovering and low velocity flight. We verify the controller perform...

Robust output-feedback simplified adaptive control model following with uncertainties and disturbances is considered. Sufficient conditions for closed-loop stability, model following performance and prescribed H∞ disturbance attenuation level are introduced, under an almost-strictlypositive-realness requirement on the plant. A numerical example, taken from the field of flight control, demonstra...

BACKGROUND Estimating the reduction in levels of infection during implementation of soil-transmitted helminth (STH) control programmes is important to measure their performance and to plan interventions. Markov modelling techniques have been used with some success to predict changes in STH prevalence following treatment in Viet Nam. The model is stationary and to date, the prediction has been o...
