In this paper, we propose three advanced digital predictive current-mode control (DPCC) algorithms based on a simplified estimation method of duty cycle lost time for asymmetric half-bridge (AHB) LED constant-current driver. They are the peak current mode control(DPPCC) algorithm leading-edge modulation, quasi-valley control(DPqVCC) trailing-edge and quasi-average control(DPqACC) double-edge mo...

Model-based predictive control that highly depends on system parameters is widely investigated. In contrast, model-free current (MFPCC) can be performed based input or output measured data, rather than any model information, hence eliminating the influence of parameter uncertainties. such a strategy, gradients due to each possible voltage vectors are stored and used predict future currents. Cur...

Predictive control strategies began to be used to solve the image based visual servoing problems. Thus, in literature, a GPC controller and a nonlinear predictive one were reported. In this paper, a predictive control strategy is developed based on a new approach for computing the feature trajectories prediction of a robot with eye-in-hand configuration. The cost function based on errors in ima...

The paper deals with the design of a predictive controller for a wastewater treatment process. In the considered process, the wastewater is treated in order to obtain an effluent having the substrate concentration within the standard limits established by law (below 20 mg/l). This goal is achieved by controlling the concentration of dissolved oxygen to a certain value. The predictive controller...

Harmonic contamination and low power factor in power systems caused by power converters have been a great concern. The effect of harmonics in current due to lagging power factor are the increase in current flow in the capacitors which results in additional heating of the capacitors and reduce its life, increased magnitudes of neutral currents in three phase systems, over-heating in transformers...

A model predictive control (MPC) scheme for a permanentmagnet synchronous motor (PMSM) is presented. The torque controller optimizes a quadratic cost consisting of control error and machine losses repeatedly, accounting the voltage and current limitations. The scheme extensively relies on optimization, to meet the runtime limitation, a suboptimal algorithm based on differential flatness, contin...

langerhans cell histiocytosis (lch) is a rare disorder described as three different entities including eosinophilic granulomaof bone, the hand-schuller-christian syndrome, and letterer-siwe disease. lch is currently classified into singlesystem lch, and multisystem lch. patients with single system lch have an excellent prognosis, and are mostlytreated with local therapy. multisystem lch is subd...
