摘要： A braking torque closed-loop control system and method for a switch reluctance motor. The closed-loop control system comprises a torque regulator, a mode selector, a current regulator, an angle optimization controller and a torque estimator. On the basis of the rotating speed of the motor, the mode selector implements a phase current soft chopper control in a low rotating speed region and an angle position control in a high rotating speed region. The current regulator performs soft chopper hysteretic current regulation. The angle optimization controller optimizes a turn-on angle and a turn-off angle of a power converter master switch to reduce torque pulsation and improve braking energy feedback efficiency. The torque estimator conducts an on-line estimation of an actual braking torque estimated value of the motor based on an actual phase voltage and current of the motor to achieve braking torque signal feedback.

摘要： A vehicular control apparatus that includes a switched reluctance motor and an electronic control unit is provided. The switched reluctance motor has a rotor and a stator and is mounted as a travel drive source in a vehicle. The electronic control unit executes current control of the switched reluctance motor. The electronic control unit executes first current control for causing the rotor to rotate in a reverse direction from a rotational direction in which the vehicle is started in the case where the vehicle is not started even when the switched reluctance motor outputs maximum torque within an allowable range, and executes control for causing the rotor to rotate in the rotational direction in which the vehicle is started after the rotor rotates in the reverse direction by the first current control to a rotation position at which torque for enabling a start of the vehicle can be output.

摘要： A full-pitch winding switched reluctance motor is provided. In this motor, one set of current components are estimated, which electromagnetically act on only one set of stator poles for one phase. Based on the estimated one set of current components, current components for respective three phases are controlled, resulting in accurate current control with no electromagnetic interactions with other phases. This current control allows a control circuit to be made compact, and a motor with effective field means can be provided.

摘要： A fault-tolerant control method for a position sensor of a switched reluctance motor, if the position sensor of the switched reluctance motor runs without a fault, detecting, in real time, four equal-interval or equal-angle continuous edge pulses of an output signal of the position sensor, the fourth edge pulse being the current edge pulse, and detecting time intervals (T1, T2, T3) between each two adjacent edge pulses sequentially, thereby calculating a time interval (T4) between the current edge pulse and a next edge pulse following the current edge pulse. If the position sensor of the switched reluctance motor fails, and the next edge pulse following the current edge pulse is lost, reconstructing the next edge pulse after the interval time (T4) of the current edge pulse of the output signal of the position sensor. The method can be used, when one or more position sensors of a rotatory and linear switched reluctance motor having various phases and various topology structures fail, to reconstruct an edge pulse after lost.
