    摘要: A control method of electromotor comprises the following steps: setting an alternating axis target current according to the rotor angle velocity of the motor and setting a direct axis target current according to the torque of the motor; detecting and collecting the three-phase currents of the electromotor, simultaneously detecting the degree of the electromotor rotor position; converting the three-phase currents of the electromotor to an alternating axis actual current and a direct axis actual current by Park conversion and Clark conversion according to the degree of the rotor position; setting the difference between the target current and the actual current as the input of the current loop, outputting the required direct axis current and the required alternating axis current by PI regulation; calculating the three-phase voltage according to the required direct axis current and the required alternating axis current output by PI regulation and the degree of the electromotor rotor position; obtaining PWM control waveform through three-phase voltage, the said PWM control waveform controlling the conversion from the direct current to the alternating current, the converted alternating current driving the electromotor.

    摘要: There is disclosed an automatic control system for limiting the operating temperature of a diesel engine (10) having a shut down lever (52) that repositions the rack of its fuel pump (12) to a shut down position that closes the pump metering valves and shuts off the fuel supply to the engine. The system includes a pyrometer (24) to sense the exhaust gas temperature from the engine and generate a signal therefrom, a temperature controller (30) having an adjustable, maximum set point temperature to receive the signal from the pyrometer (24) and to generate a control signal which is applied to a control valve (102) in a fluid pressure line (99) which applies fluid pressure to a pressure responsive actuator (82) that moves the shut down lever (52) a fraction of its full travel necessary for shut down and thereby repositions the fuel pump rack to a throttling position in response to a sensed exhaust gas temperature which exceeds the preselected maximum set point temperature.

    摘要: La présente invention a pour objet un procédé d'entraînement en rotation d'un rotor principal (2) d'un giravion (1). Une consigne de régulation (C) d'un groupe de motorisation (3) provoquant un entraînement du rotor principal (2) à vitesse de rotation variable est générée par une unité de commande (4) et est transmise à une unité de régulation (5) du fonctionnement du groupe de motorisation (3). La valeur d'une consigne initiale (NR ini ) est générée progressivement en continu selon la variation de la valeur courante de la densité (D) de l'air extérieur ambiant du giravion (1). La valeur de la consigne initiale (NR ini ) est potentiellement corrigée selon des conditions de vol du giravion (1) prédéfinies. Préalablement à sa transmission à l'unité de régulation (5), la valeur de la consigne de régulation (C) est de préférence limitée dans une plage de vitesses tolérées d'entraînement en rotation du rotor principal (2).
