Embodiment Construction

[0045] According to the specific experiments and combined Figure 4 , the present invention will be further described.

[0046] The experimental prototype uses a 12 / 8-pole three-phase switched reluctance motor with a rated power of 4kW and a rated speed of 2200rpm.

[0047] Microcontroller 1 uses single-chip microcomputer STM32F103RBT6, and C1, C2, and C3 use voltage-type Hall current sensors, which can transmit three-phase current signals to the single-chip microcomputer. The single-chip microcomputer converts the analog signal into a digital signal through the A / D conversion module for internal program processing. The position detection unit is composed of the rotor position measurement tooth plate, three slot-shaped Hall switch devices and corresponding circuits. The MCU obtains the state of the three Hall switches through the input capture interrupt, so as to determine the current position of the rotor.

[0048] The control program adopts the control strategy of the pre...

Abstract

The invention provides a control method for simultaneously suppressing torque ripple and vibration of a switched reluctance motor, and belongs to the technical field of switched reluctance motors. According to the invention, three objects, namely, the rotating speed, the torque and the radial force, can be controlled, the output torque of the motor is enabled to be smoother and the torque pulsation is enabled to be obviously reduced under the condition that the motor is ensured to have good rotating speed characteristics, and the motor is ensured to operate more stably and efficiently in an electrical transmission system. Meanwhile, the radial vibration of the switched reluctance motor stator is effectively reduced, so that the generated vibration noise is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of switched reluctance motors, and relates to a control method for simultaneously suppressing torque ripple and vibration of switched reluctance motors. Background technique [0002] As a new type of special motor, switched reluctance motor (SRM) has the characteristics of simple and firm structure, good speed regulation performance, many controllable parameters, high starting torque, low starting current, and is suitable for harsh environments, so it shows broad potential Application prospects. [0003] However, the switched reluctance motor has its inherent disadvantages, that is, there is a large torque ripple and vibration noise. When the switched reluctance motor is running at a low speed, it often produces a large torque ripple, which is mainly affected by the switching form and nonlinear factors. The vibration noise of the switched reluctance motor is mainly caused by the radial vibration of the sta...
