Embodiment 1

[0077] Such as figure 1 As shown, the position control method of a drum washing machine according to an embodiment of the present invention is applicable to a drum washing machine, and the method includes: step 102, generating an operation control command of the motor according to a preset vector control model; Run the control command to control the motor during the reciprocating operation between the initial angle and the target angle, and detect whether the feedback speed of the motor feedback is greater than the preset speed limit threshold; step 106, when it is detected that the feedback speed is greater than the preset speed limit threshold, The running control instruction is updated according to the preset speed limit threshold, so that the feedback speed of the motor decreases to be less than or equal to the preset speed limit threshold.

[0078] In this embodiment, the operation control of the motor is carried out through the preset vector control model, which is diffe...

Embodiment 2

[0104] Such as image 3 As shown, when it is detected that the feedback speed is greater than the preset speed limit threshold, the operation control instruction is updated according to the preset speed limit threshold, so that the feedback speed of the motor drops to less than or equal to the preset speed limit threshold, specifically including:

[0105] The main control module of the drum washing machine is used to send the drum position control command θ ref , which is the target angle.

[0106] The position controller 302 is used to receive the master control position instruction θ ref and with the motor position θ fdb Generate speed control command ω ref ;

[0107] Speed ​​calculator 308, used to obtain the feedback speed ω fdb , that is, the above ω c ;

[0108] A speed limit threshold command generating module 318, configured to generate a preset speed limit threshold ω ref ';

[0109] The speed limit module 316 is configured to limit the speed control command ...

Embodiment 3

[0127] Such as Figure 4 As shown, when the feedback speed is detected to be less than the preset speed limit threshold, the operation control command generated according to the target angle is used to control the motor operation without the intervention of the speed limit module. The vector control model specifically includes:

[0128] The main control module of the drum washing machine is used to send the drum position control command θ ref ;

[0129] The position controller 402 is used to receive the master position instruction θ ref , and with the motor position θ fdb Generate speed control command ω ref ;

[0130] Speed ​​calculator 408, used to obtain the feedback speed ω fdb , that is, the above ω c ;

[0131] The speed controller 404 is used to control the instruction ω through the speed ref and feedback speed ω fdb Generate torque control command T asr ;

[0132] The current controller 406 is used to control the instruction T through the torque asr with fe...

Abstract

The present invention provides a position control method and control device, a roller washing machine and a storage medium. The position control method of the roller washing machine comprises the steps of generating an operation control instruction of a motor according to a preset vector control model; in a process of controlling the motor to reciprocate between an initial angle and a target angleaccording to the operation control instruction, detecting whether the feedback speed of motor feedback is greater than a preset speed limit threshold or not; and when it is detected that the feedbackspeed is greater than the preset speed limit threshold, updating the operation control instruction according to the preset speed limit threshold, thereby reducing the feedback speed of the motor to be less than or equal to the preset speed limit threshold. By the technical scheme, clothes wear is reduced while the clothes washing function is realized.

Description

technical field [0001] The present invention relates to the field of motors, in particular to a position control method for a drum washing machine, a position control device for a drum washing machine, a drum washing machine and a computer-readable storage medium. Background technique [0002] In the washing mode in the related art, the clothes in the drum are washed by beating them. When this washing mode is used for washing, some clothes are washed too roughly, resulting in serious wear of the clothes after washing. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related art. [0004] For this reason, an object of the present invention is to propose a new position control method of the drum washing machine of the drum washing machine. The operation control of the motor is carried out through the preset vector control model, which is different from the "controlling the motor positiv...
