The present disclosure provides an electronic device and a method for controlling data updates of the electronic device, the electronic device comprising: a control portion including a storage configured to store data and a controller configured to control data updates in the storage; a power supply portion; a power storage portion configured to be connected with the power supply portion, receive and store electric power of the power supply portion, and supply the electric power to the control portion; and a power supply detection portion configured to detect whether the power supply portion supplies power normally, the storage includes a first storage portion configured to store start-up data for electronic device start-up and a second storage portion configured to store running data for electronic device running after start-up; in the process of updating the start-up data of the first storage portion, if the power supply detection portion detects the power supply portion has a power supply abnormality, the controller controls the storage to complete the process of updating the start-up data by using the electric power stored in the power storage portion.

Electronic device and method for controlling update of data in electronic device

A control device and a control method for an induction motor. The control device comprises: a magnetizing current adjusting unit used for calculating a magnetizing voltage instruction; a torque current adjusting unit used for calculating a torque voltage instruction; a flux linkage instruction angle generating unit calculating a flux linkage instruction angle according to a lower limit &#x3c9;of a preset stator frequency, a stator frequency &#x3c9;, and a flux linkage estimation angle; and a motor stator voltage instruction calculating unit calculating, according to the magnetizing voltage instruction, the torque voltage instruction, and the flux linkage instruction angle, a stator voltage instruction for controlling a stator of the motor. The control system can be run outside an unstable area, and the stability of control by the control device is improved.
