Invention relates to the field of electric engineering and power electronics. A method for control of a three-phase voltage inverter with current stabilisation at transfer to overload mode consists in generation of two preset signals for two load voltage orthogonal projections, the preset signal of overload current is shaped, the reference bidirectional signal is shaped, control signals are generated in two orthogonal projections against the preset signals and feedback signals, the control signals in two orthogonal projections are converted into three modulating signals in the temporary area, pulses are generated for control of the voltage inverter gates when the modulating voltage exceeds the reference voltage, phase current instantaneous values are measured for the voltage inverter, an amplitude of the generalised vector for phase currents is calculated for the voltage inverter and when it reaches the preset value, the preset overload voltage signal is corrected so that current equal to the overload current preset signal is generated for the load. Thus, in the overload mode load current stabilisation is provided at the level defined by the setting. At that smooth transition is ensured from the normal mode to the current limiting mode and vice a versa, i.e. regulators all the time operate in a linear mode (they are not limited), and only the voltage preset signal changes. |

The temperature-sensitive bridge is connected to the inputs of the operational amplifier which is switched on with positive feedback. The output of the operational amplifier is connected to the gate of the first transistor. The source of the latter is connected to the voltage stabiliser and the drain - to the common point. The drain of the second field-effect transistor is connected to the output of the operational amplifier and the gate of the first field-effect transistor, and the gate of the second field-effect transistor is connected to the source of the first field-effect transistor. The second thermistor is set between the drain and the source of the second field-effect transistor. |

Method of controlling inertial antenna drive Method of controlling an inertial drive of an antenna includes generating a tracking error signal on the target bearing by subtracting the estimate of signal of the turning angle of the antenna from the estimate signal of the target bearing and amplification thereof with a gain coefficient which depends on properties of the antenna drive; generating tracking error signals from all target bearing derivatives estimated in the filter of an angle metre by subtracting the estimate signal of each derivative of the turning angle of the antenna from the estimate signal of each target bearing derivative; amplifying each of said tracking error signals on the target bearing derivatives with different gain coefficients which depend on properties of the antenna drive and addition thereof with the amplified tracking error signal on the target bearing to form an antenna drive control signal. In order to generate an antenna drive signal, gain coefficients are varied on each probing pulse synchronously with probing pulse transmissions. |

Method for monitoring vessel insubmersibility Method for monitoring vessel insubmersibility consists in measuring in measurement unit (1) following parameters: vessel angular motions (2) and accelerations (3) relative to longitudinal and lateral central axes, linear motions (4) and (5) determining fore and aft drafts, vessel rolling motion period of encounter (6), angle of encounter (7), vessel speed (8), linear motions and accelerations (9) relative to vertical central axis, levels of liquid in flooded compartments (10). Based on measurements, informational vector of measurements is generated, immersion case is determined, "sliding window" is chosen, rolling and pitching modes are set, equilibrium parameters of injured vessel sitting are determined, marginal values of sitting parameters are chosen, injured vessel and damage stability condition is evaluated, measures for vessel aligning and stability recovering are implemented. |
