In single-phase inverters, the proportional control is paralleled with the repetitive control to improve the dynamic performances. Meanwhile, in order to guarantee the stability of system, the static error cannot be eliminated in this control. This paper proposed an advanced scheme for the repetitive control to achieve zero error tracking. Taking the advantage of comb filtering by using Fourier transform...
The article aim at a typical speed reducer measuring points (failure-prone region) of main feed belt for the blast furnace to find the developing trend of the equipment malfunction and to make more accurate judgments for equipment malfunction, according to measurement data on many occasions. At the same time, a corresponding vibration diagnostic criteria of the equipment and a common fault intelligent...
