Electrical characteristic experiments show that the discharge duration, the evolution of the gliding arc and the fracture frequency are affected by the pressure difference between the inlet and outlet of the igniter (∆p). With the increase in ∆p, the frequency of the trapezoidal envelope in ...
First, based on the broadband that is typical of blast waves, the peak frequency of the P-wave was obtained in the time–frequency domain, taking advantage of the difference in the propagation speed of the P-wave, S-wave, and the surface wave. Second, the phase difference between two ...
In Section 4, by the simulation experiments, comparison between the DTC and the proposed FADFC strategy illustrates that the steady-state performance can be obviously improved by utilizing the proposed strategy. Finally, Section 5 is the conclusion. 2. Brushless Doubly Fed Machine (BDFM) Model ...
