摘要： An actuator driving device drives an actuator connected to an output terminal. The control unit of the actuator driving device includes a PWM delay time setting unit, a first duty ratio setting unit, and a second duty ratio setting unit. The PWM delay time setting unit sets a delay time of pulse width modulation control for a driving voltage to be applied to the output terminal and outputs setting information to the first and second duty ratio setting units. The first duty ratio setting unit sets the first duty ratio for a first PWM output unit, and the second duty ratio setting unit sets the second duty ratio for a second PWM output unit. When positive and negative energization is performed, the control unit controls to reduce the amount of change in current in the current peak of a PWM waveform by providing a short-circuit period in response to the energization amount.

摘要： A four-phase switched reluctance motor torque ripple three-level suppression method. A first set of torque thresholds is set in rotor position interval [0°, θr/4]. A second set of torque thresholds is set in rotor position interval [θr/4, θr/2]. Power is supplied to adjacent phase A and phase B for excitation. The power supplied for excitation to phase A leads the power supplied for excitation to phase B by θr/4. An entire commutation process from phase A to phase B is divided into two intervals. In rotor position interval [0°, θ1], phase A uses the second set of torque thresholds while phase B uses the first set of torque thresholds. Critical position θ1 automatically appears in the commutation process, thus obviating the need for additional calculations. Total torque is controlled between [Te+th2low and Te+th2up]. In rotor position interval [θ1, θr/4], phase A continues to use the second set of torque thresholds, phase B continues to use the first set of torque thresholds, and the total torque is controlled between [Te+th1how and Te+th1up]. This suppresses torque ripples of a four-phase switched reluctance motor and provides great engineering application values.

摘要： A system is configured to receive vehicle state input, and in response to the vehicle state input, select an operational mode for PWM switching of electronics in a power conversion circuit of a hybrid electric vehicle electric drive system (EDS). Vehicle state input can pertain to EDS state, engine state, and the presence of alternative noise sources, such as audio equipment, climate control equipment, and lowered windows. Various operational modes can include a noise reduction mode in which EDS noise is reduced, a loss reduction mode in which EDS losses are reduced, and a default mode, which can be designed to maximize fuel efficiency. A system can be configured to provide a PWM implementation strategy based on operational mode selection. By way of example, a PWM implementation strategy can comprise random PWM, continuous PWM, discontinuous PWM and fixed frequency PWM.

摘要： A control device of a three-phase AC motor includes: an inverter that drives the AC motor; a current sensor that senses a current flowing in a sensor phase of the AC motor as a sensor phase current; and a controller that switches on and off a switching element of the inverter to control a current flowing through the AC motor. The controller includes: a current estimation device that estimates d-axis and q-axis current estimated values based on the sensor phase current and an electric angle of the AC motor; and a zero-crossing interpolation device that interpolates a command value relating to a voltage of the AC motor when the sensor phase current is in a zero cross range, which includes a zero point. When the sensor phase current is in the zero cross range, the zero-crossing interpolation device interpolates the command value with a continuous variable value.

摘要： An AC motor controller is provided that utilizes a direct torque controller and primary and secondary control loops. The primary control loop operates in a relatively conventional manner, determining a voltage vector that sets the inverter switching variables for the motor's power inverter, where the voltage vector is based on the motor's torque and flux as estimated from the measured voltage and current of the motor. The secondary loop, utilizing a faster sampling rate than the primary loop, estimates a more up-to-date torque error which is compared to a secondary torque error band, where the secondary torque error band is preferably narrower that the primary torque error band. If the secondary loop determines that the up-to-date torque error has exceeded the secondary torque error band, it sets a null voltage vector, thereby limiting torque ripples.

摘要： An embodiment of a motor controller includes first and second supply nodes, a motor-coil node, an isolator, a motor driver, and a motor position signal generator. The isolator is coupled between the first and second supply nodes, and the motor driver is coupled to the second supply node and to the motor-coil node. The motor position signal generator is coupled to the isolator and is operable to generate, in response to the isolator, a motor-position signal that is related to a position of a motor having at least one coil coupled to the motor-coil node. By generating the motor-position signal in response to the isolator, the motor controller or another circuit may determine the at-rest or low-speed position of a motor without using an external coil-current-sense circuit.

摘要： The invention relates to an electronically commutated electric motor with a stator and a rotor, which is designed as a permanent magnet rotor in particular. The electric motor also has a control unit which is connected to the stator. The control unit is designed to generate control signals for energizing the stator coils of the stator in order to generate a rotational magnetic field. The electric motor is designed to at least partly compensate for a torque ripple of a torque generated by the rotor. According to the invention, the electric motor has a rotor position sensor and a current sensor. The current sensor is designed to detect currents flowing in the stator coils and to generate a current signal which represents the currents. The control unit preferably has a processing unit which is designed to ascertain harmonics of the electromotive force dependent on the current signal, a voltage applied to the stator coils, and a rotor position signal generated by the rotor position sensor and to generate a control signal which compensates for the effect of the harmonics. The control unit, in particular the processing unit, is designed to superimpose the compensating control signal with the control signal so as to completely or at least partly compensate for the effect of the harmonics and thus the torque ripple.

摘要： A method is described for controlling a multiphase machine which is connected to a battery, the multiphase machine having a DC link which is provided with a DC link capacitor, phase windings, and a high side switch and a low side switch for each phase. The switches associated with the individual phases are controlled by a control unit in such a way that sinusoidal phase currents are predefined, at least one phase current is connected at any point in time in each control cycle, and a fixed, pulsed control pattern is present for each control cycle. The control widths of the actuating signals associated with the phases are constant in the pulsed control pattern. The control pulses associated with the individual phases are predefined in such a way that the DC link current which arises is minimized.
