DEVICE, METHOD AND PROGRAM FOR AUTOMATIC CONTROL COMPUTERS FOR ELECTROMAGNETIC DAMPERS |
摘要 |
Automatic control device (30) (30′) (30″) for an electromagnetic damper of vibrations (50) having windings (51) arranged around a rotor (62) of a rotating machine (60) and supplied by an electric signal; the electromagnetic damper of vibrations also having a magnetic circuit (54), constituted by a first part (54a) and a second part (54b) separated between them by an air gap (54c). The automatic control device (30) (30′) (30″) includes: amplification stages (32) (32′) (32″) for supplying the windings (51) and having at least an output (32a) (32′a) (32″a); signal processing stages (31) (31′) (31″) electrically connected to the amplification stages (32) (32′) (32″). The signal processing stages (31) supply the amplification stages (32) (32′) (32″) on the basis of an electric signal (a(t)) of voltage and/or current drawn on at least one output (32a) (32′a) (32″a); by one or more sensible elements (34) remote in comparison with the rotor (62) and variable as an inductance of the windings (51) varies. |
