A method of controlling an overly determined actuator system that has a first number of actuators (α.sub.i) which is greater than a second number of the actuators needed to perform a predetermined physical task. The method includes: automatically controlling the first number of actuators by a control unit (CU) for jointly performing the predetermined physical task; repeatedly checking a functional state of the first number of actuators to detect an actuator failure of any one thereof; in case of any detected actuator failure, generating at least one emergency signal (EM) representative of an adapted physical task to be performed by a remaining number of the actuators. The emergency signal is generated based on kinematics of the actuator system, on known physical capacities at least of the remaining actuators, and optionally on a computational performance model of the actuator system. The adapted physical task includes activating each of the remaining actuators below a predetermined threshold of maximum physical load on a respective actuator and activating the ensemble of remaining actuators in a way to prevent further damage to the actuator system. An emergency control system and an aircraft are also provided.

When the rotation direction of a motor is determined by a connection determination unit not to match a rotation command, the phase sequence of a current detection signal and the phase sequence of a voltage command are changed by a phase sequence change unit, or the positive/reverse polarity of an encoding signal outputted from an encoder is inverted by the phase sequence change unit, whereby the rotation direction of the motor controlled by a motor control device can match the rotation command.
