摘要： A motor control device includes a motor drive circuit and a microcomputer that controls the drive circuit. The microcomputer generates a control signal on the basis of duty command values Du, Dv, and Dw to control the drive circuit. The microcomputer includes a dead time compensation section that corrects the duty command values Du, Dv, and Dw on the basis of dead time compensation values Ddu, Ddv, and Ddw. The dead time compensation section includes a basic compensation value computation section that computes a basic compensation value Dd as a fundamental value of the dead time compensation values Ddu, Ddv, and Ddw, and a filter section that performs a filtering process corresponding to a low-pass filter on the basic compensation value Dd. The dead time compensation section sets the dead time compensation values Ddu, Ddv, and Ddw on the basis of an output value α from the filter section.

摘要： A power output apparatus including a power source, an electric motor and a connecting and disconnecting device, and a method of controlling the power output apparatus, are provided. When load driving force is applied from the power source to a power shaft in a condition where the power shaft and a driveshaft are disconnected from each other by the connecting and disconnecting device, lock control is executed to control the motor by fixing a direction of a magnetic field of a stator so as to restrict rotation of a rotor. When the rotor rotates during execution of the lock control, rotation retardation control is executed to control the motor by rotating the direction of the stator magnetic field in accordance with rotation of the rotor, so that driving force is applied from the motor to the power shaft in a direction opposite to that of the load driving force as driving force applied from the power source to the power shaft.

摘要： When a fault of any one of phases is detected by a fault detector, each of the phases is checked for fault on the basis of fault detection information input to a controller, and the phases of normal phase currents which have been judged to be not faulty by a faulty phase discriminator are varied such that a current vector obtained by decomposing the normal phase currents into orthogonal X- and Y-axis components to derive resultant currents and then combining the resultant currents follows a nearly circular locus.

摘要： In switching between asynchronous PWM control and synchronous PWM control, control can be simplified. An apparatus has a first pulse pattern generation processing module which generates a synchronous PWM signal in a first pulse pattern formed of multiple pulses defined in accordance with two or more parameters based on a voltage command value, and a second pulse pattern generation processing module which generates a synchronous PWM signal in a second pulse pattern formed of a single pulse. The first pulse pattern generation processing module modifies the individual parameters in switching pulse patterns between the first pulse pattern and the second pulse pattern. The individual parameters are modified to move the pulse patterns, and thus control can be simplified.

摘要： An electrical propulsion system includes an electrical motor configured to drive one or more propellers of the aircraft, a capacitor configured to stabilize a direct current (DC) bus voltage, a first inverter circuit coupled to the capacitor and configured to convert the DC bus voltage to alternate current (AC) voltages to drive a first set of stator windings of the electrical motor, in response to a first pulse width modulation (PWM) vector, and a second inverter circuit coupled to the capacitor and configured to convert the DC bus voltage to AC voltages to drive a second set of stator windings of the electrical motor, in response to a second PWM vector. The first PWM vector and the second PWM vector are substantially equal and opposite vectors.
