It is shown that allpole filters of secondand third-order can be significantly desensitized to component tolerances by so-called impedance tapering, i.e., successively impedance-scaling upwards the Lsections of a resistance–capacitance ladder network in the forward and feedback path of a single-amplifier active filter. In order to obtain a realizable filter, certain constraints on the design eq...

Removal rate and durability are the two most important parameters of an ideal air purification filter to remove inhalable particles toxic gases. Here, based on interaction a local electric field external field, novel coaxial core–shell CuO@NH2-MIL-53(Al) nanowire array was synthesized rigid copper net, which used PM2.5 SO2 simultaneously. The removal rates by with without can reach 98.72% 44.41...

The general principle underlying the method described below is that of deviation electrophoresis. The mixture of ions to be spearated from each other enters an electric field in form of a thin streak carried by a buffer flow transversely to the electric field. The streak is affected by the electric field similarly to a zone in zone electrophoresis. The different ions are moved by the electric f...

Electric vehicle (EV) charging stations draw nonlinear currents, which makes the distribution network unbalanced, distorted, and results in power quality (PQ) issues. These PQ issues are mitigated this work through high-performance control of shunt active filter (SAPF). In proposed method, a linear Kalman (LKF) has been applied to grid voltage load current signals for harmonic disturbance robus...

Accurate and real-time acquisition of vehicle state parameters is key to improving the performance control systems. To improve accuracy parameter estimation for distributed drive electric vehicles, an unscented Kalman filter (UKF) algorithm combined with Huber method proposed. In this paper, we introduce nonlinear modified Dugoff tire model, build a three-degrees-of-freedom time-varying paramet...
