Title: Method and control device for controlling asynchronous induction motor
Inventor: ZHANG ZHENYU
IPC: H02P21/02
Filed: 2023-05-09
Abstract: The present invention relates to motor control technology, in particular to a method for controlling an asynchronous induction motor, a control device (610) for implementing the method, a motor system including the control device, and a computer-readable storage medium on which a computer program for implementing the method is stored. The method for controlling the asynchronous induction motor according to some embodiments of the application comprises: A. determining (302) a target value of d-axis current according to a target value of q-axis current of the asynchronous induction motor; B. determining (303) a correction value of the target value of the d-axis current based on q-axis voltage and d-axis voltage of the asynchronous induction motor; and C. determining (404) target values of the d-axis voltage and the q-axis voltage of the asynchronous induction motor based on the correction value of the target value of the d-axis current and the target value of the q-axis current. In the above embodiment, through the feedback mechanism based on voltage amplitude, the flux current can be controlled adaptively, and the motor efficiency can be improved without sacrificing torque performance. In addition, because the control logic does not involve motor parameters, it has strong robustness.

Abstract: Die Verzögerungsschaltung einer Innenraumbeleuchtung eines Kraftfahrzeugs ist über einen Türkontakt einzuschalten. Die Verzögerungszeit läßt sich durch ein RC-Glied bestimmen. Eine derartige Schaltung soll die übliche Funktion der Innenraumbeleuchtung nicht beeinträchtigen und einfach an das Bordnetz des Kraftfahrzeugs anzuschließen sein. Es wird hierfür das RC-Glied und ein Schaltverstärker parallel zu einem Türkontakt gelegt. Die beim Öffnen des Türkontakts am durchgeschalteten Schaltverstärker abfallende Restspannung lädt den Kondensator des RC-Gliedes. Diese Restspannung ist einerseits größer als die Schwellwertspannung eines Schwellwertschalters und andererseits so klein, daß die Differenzspannung zwischen der Batteriespannung und der Restspannung zum Betrieb der Lichtquelle ausreicht: Durch einen einzigen zusätzlichen Schaltungsanschluß kann bei eingeschalteter Außenbeleuchtung die Verzögerungszeit wesentlich verkürzt werden. Außerdem kann durch einen weiteren einzigen Schaltungsanschluß bei eingeschalteter Außenbeleuchtung ein Warnsignal abgegeben werden.

Abstract: Coincident current windings on a magnetic print head are driven in a special sequence to minimize undesired spurious printing effects otherwise caused by undesirable concentrations of magnetic flux. Rather than energizing all digit windings (in accordance with supplied data values) for each successive energization of a word winding, the digit windings are driven in multiple sub-sets or groups. Only one such sub-set is energized at any given time and the members of each sub-set are chosen to minimize undesired spurious magnetic flux distributions for any given magnetic printing head configuration.

Abstract: Safety handrail and access ladder with retractable rungs to dissuade use without prior authorisation. Originally developed for hydrocarbon-transporter tanker vehicles but extendable to all fields where, on safety grounds, it is desirable to prevent access if a handrail for protecting against the risks of falling has not been installed beforehand, the principle refers to the following invention: The safety handrail is a parallelogram which can be folded up when travelling so as to keep the bulk of the equipment within agreed or statutory limits. An access ladder, several rungs of which are located in an area where there are no protuberances which can form substitute treads and which are retractable, which ladder is associated with the handrail. If access is required, a hydraulic, electro-hydraulic, pneumatic or other type of pump should be operated, the said pump feeds a jack which actuates the safety rail unit and, by slaving, places the rungs of the access ladder in a position in which they can be used. The characteristic elements of the innovation are:   - Access ladder rungs which can be retracted in a region where their absence forms a major obstacle to any type of access (DISSUASION).   - Special interconnection between access ladder and SAFETY rail, such that the use of the former requires the latter to be placed in a service position.   - Control on the ground, such that it is virtually impossible to begin any ascent before the safety assembly is in position.   - Hydraulic or pneumatic transmission which guarantees stable positioning of the various elements and safeguards against risks of wear or spurious noises when travelling. <IMAGE>

Abstract: An impending kickback condition in the operation of a power tool or machine tool system is sensed and used to control or eliminate the kickback. The ability to sense an impending kickback condition can be used in all categories of power driven tools. The change in force applied to the power driven tool or other implement is monitored by measuring the rate of change of speed of the tool or implement, and if the speed is decreasing, the rate of change of speed is compared with a threshold value which may be either preset or variable. If this threshold value is exceeded, an output control signal is generated which inhibits the coupling of power to the tool or other implement and/or applies a brake to stop the tool or implement. In order for power to once again be coupled from the motive.power source to the shaft, the start switch must be opened and then reclosed or some other signal provided by the operator or another predetermined condition must be met.
