摘要： The invention relates to a process for estimating an instantaneous resistance in a phase winding in a reluctance machine. The process comprises the steps of: receiving a signal (Udm) indicating a voltage (UW) across at least one phase winding; receiving a signal (iWm) indicating a current (iW) through the phase winding; estimating a magnetic flux in response to the voltage signal and the current signal; estimating an instantaneous resistance (RW) in the phase winging in accordance with a phase relation between the current signal (iWm) and the magnetic flux signal (&PSgr;est). The invention also relates to a method for controlling an electrical machine and a drive system for performing the method.

摘要： The present invention is a motor control device for controlling current command values in relation to a permanent magnet reluctance motor which generates torque corresponding to the combined value of the torque resulting from the permanent magnet and the reluctance torque through field-weakening control in such a manner that the motor terminal voltage does not exceed the maximum inverter output voltage. In particular it controls the angle of the current relative to the motor rotor which is required for the purpose of field-weakening control, and ensures that this is stable and effective whatever torque is output.

摘要： A controller for use in a switched reluctance (SR) motor drive is provided. The controller includes a DC—DC converter coupled to an inverter. The DC—DC converter can be a buck converter, a boost converter, or a buck-boost converter. The control parameters to the DC—DC converter can be optimal. In addition, the bus voltage of the motor drive can be reduced to a level such that the motor operates in single pulse mode. A capacitor can be connected in parallel across the outputs of the DC—DC converter supplying the inverter. Using the DC—DC converter to indirectly profile the phase current can reduce motor torque ripple.

摘要： A controller K calculates a command torque by correcting the required torque w1 with a correction based on a motor rotation speed Nm, and controls an electric motor based on the command torque T. The command torque w1 is regarded as one content of an outside input W to the controller K. A difference between the rotation speed of the electric motor outputted by the actual model describing an actual response of the electric motor and another rotation speed of the electric motor outputted by a reference model describing ideal performance and vibration reduction is regarded as one content Z1 of controlled output Z from the controller K. Moreover, a characteristic variation depending on vehicle types and so on, a torque ripple, and a sensor noise are described by weight functions wm1, wm2 and wn. Then a pertubative output w2 and a sensor noise w3 are regarded as the remaining contents of the input W. An output of the weight function wm2 is regarded as the controlled output Z. The controller K is determined by solving H∞control problem that a transfer function between the outside input W and the controlled output Z is determined as an H∞norm of the transfer function to be smaller than a predetermined value.

摘要： A reluctance type motor apparatus comprises switching devices for energizing phase coils of a motor, diodes for circulating discharge currents of the phase coils, a current sensor for detecting a sum of currents flowing in the phase coils, and a control circuit for controlling energization of the phase coils so that the detected sum of the currents equal a predetermined reference current. The current sensor is positioned between the phase coils and junctions between the phase coils and the diodes. Phase currents supplied to energize the phase coils are varied in dependence on the rotational position of the rotor so that the output torque of the motor does not include ripple.

摘要： A system and method to smoothly limit the top speed of the generator motor at which power is provided. The system according to this invention consists primarily of an engine, which supplies mechanical power to a switched reluctance motor with position sensing capability, which delivers electrical power to an inverter. The inverter contains a digital signal processor (DSP) controller to control the delivery of electrical power to the battery in the generation mode. Signal information regarding motor speed and current is delivered from the switched reluctance motor with position sensing capability to the DSP controller and signal information regarding current and voltage is delivered from the battery to the DSP controller. In the preferred embodiment, the switched reluctance machine will have position sensing capability to monitor the position of the rotor in relation to the stator, and sensors to monitor the phase currents and bus current. A digital signal processor (DSP) will be used in order to meet the precise position-based control requirements. Therefore, since the position and current is monitored and controlled in real-time by the DSP, the power output in the generation mode can be actively reduced as the speed increases or disabled at a certain maximum speed.
