  • Patent number: 9515578
    Abstract: A control method to be implemented in a power converter, the power converter including an inverter module controlled by a control rule that makes it possible to determine a control voltage to be applied to an electrical load on the basis of a reference control voltage. The control method includes determining a correction value to be applied to the reference control voltage, the correction value being determined from a first filtered voltage obtained by filtering a voltage that is representative of the real measured voltage, and a second filtered voltage obtained by filtering a voltage that is representative of the reference control voltage.

  • Publication number: 20130287596
    Abstract: The invention relates to a method and a system for controlling a centrifugal pump (1) actuated by an electric motor (2). The control method comprises: a first step of selecting a speed and of controlling the variable speed drive (3) in order to apply said speed to the electric motor (2), a second step of controlling the solenoid valve (6) over the whole of its operating range at said selected speed, a third step of measuring the pressure and the flow rate of the fluid flowing in the pumping circuit and of measuring the electric power supplied to the motor for each operating point of the solenoid valve (6), a fourth step of determining, for said selected speed, the pressure curve as a function of the flow rate and the curve of the power supplied as a function of the flow rate.
