    Abstract: Multipliers 21a and 21b output values, which are obtained by multiplying a total drive command value Es by first and second gains G1 and G2, respectively, as first and second drive command values E1 and E2. Controllers 23a and 23b control first and second actuators (motors) 5 and 7, respectively, on the basis of the first and second drive command values. The detection values of the drive amounts of the actuators are denoted by Ef1 and Ef2, respectively, and the detection value of the drive amount of a driven body is denoted by Ef. A gain calculator 27 calculates the gains G1 and G2 on the basis of Ef1, Ef and Ef2. An upper limit value of Ef, which denotes the drive amount of the driven body, is denoted by Lmax. When Ef1, Ef2 or Ef approaches zero, the first gain G1 is brought close to (Ef1−Lmax/2)/(Ef−Lmax).

    Abstract: A 0-axis current calculator 7 configured to calculate a target value of the 0-axis current by setting the current of the open phase to be zero when one of the phases becomes open, or determines that the target value of the 0-axis current is zero when there is no open phase is provided. Based on the target values of the d-axis current and the q-axis current, the target value of the 0-axis current calculated by the 0-axis current calculator 7, and the d-axis current, the q-axis current, and the 0-axis current transformed by the d-q-0 transformer 8, the current supplied to each phase of the motor are controlled.

    Abstract: An aircraft electric actuator drive apparatus has an electric actuator and a secondary power supply device. The electric actuator is driven using electric power from a main power unit provided in an aircraft. The secondary power supply device can temporarily supply electric power to the electric actuator while electric power from the main power unit is applied to the electric actuator.
