Abstract: The invention relates to a current-compensating device able to be connected, in shunt configuration, between an electrical network and non-linear and linear electrical loads and downstream of at least one renewable-energy-generating power unit coupled to an energy-storing element, the compensating device including: a power converting unit including at least one voltage inverter able to generate an AC current; an output filtering unit, including one filter dimensioned to block the harmonic components due to the switching of the inverter; a control unit comprising a unit for computing reference currents and a switch driving device that controls the switching of the inverter as a function of the identification of the currents by the unit for computing the reference currents.

Abstract: Higher Order Sliding Mode (HOSM) control techniques are applied to the Guidance Control (G&C) of interceptor missile in which velocity may be steered by combination of main thrust, aerodynamic lift and lateral on-off divert thrusters, and attitude may be steered by continuous or on-off actuators. Methods include the pointing of the seeker, its associated estimation processes, a guidance law that uses concurrent divert mechanisms, and an attitude autopilot. The insensitivity of the controller to matched disturbances allows the concurrent usage of the divert mechanisms without adverse effect on the accuracy. The controller also allows the de-coupling of the control of roll, pitch and yaw channels, and usage quaternions to represent body attitude and it provides control perfect robustness. While it conceivable to design separately the components of the G&C method, it is widely accepted that designing them in an integrated fashion usually produces a better result.
