Deadbeat control method for a three-phase inverter with an RLC filter, storage means for said method and railway vehicle

摘要

The method involves calculating a setpoint for average intensity of direct current traversing an output point of a low pass resonant filter between two consecutive instants. The setpoint is established from discrete state equations of the filter so that voltage is equal to preset voltage setpoint at one of the instants. An electric converter is controlled to produce current traversing the point of the filter whose average intensity between the instants is equal to current setpoint, where time interval between the instants is lesser than five times of stator time constant. Independent claims are also included for the following: (1) a method for controlling a line current traversing an inductor of a low pass resonant filter (2) an electric vehicle comprising a traction motor (3) an information recording medium comprising instructions to perform a method for controlling voltage between two output points of a low pass resonant filter.
