ECPT is a novel technology which utilizes capacitive coupling to realize wireless energy transfer. But, it is well known that ECPT system is very sensitive to parameters variation. In order to improve system robustness, a novel quasi sliding mode control method is proposed. A GSSA model is building up and a quasi sliding mode variable structure control strategy is proposed accordingly. Finally, the...
Summary form only given. A synthetic jet actuator (SJA) with different exits and the piezoelectric (PZT) vibrator in clamped and simply supported edge conditions is modeled using lumped elements. The equivalent circuit of the SJA and the frequency-response function of the circuit are established to analyze the frequency behavior of the SJA. Results show that the PZT vibrator parameters, the actuator...
In the present paper, a new electromagnetic bandgap (EBG) structure is proposed to design and fabricate low-pass filters on coplanar waveguide (CPW). Using the novel EBG structure, the filter prototypes exhibit sharp cutoff and low insertion loss in the passband. An equivalent lumped L-C circuit mode is introduced to describe the proposed EBG structure, which manifests an elliptic-function low-pass...
