Abstract: A power control system includes a current sensor and a control unit. The current sensor is coupled to a permanent magnet synchronous motor (PMSM) and is configured to monitor a current profile of the PMSM. The control unit is coupled to the PMSM and a magnetic bearing system. The control unit receives signals associated with the current profile of the PMSM and controls power provided by a main power supply to the PMSM in a first operating mode. In response to detecting a power failure of the main power supply, the control unit determines an estimated rotation speed of the PMSM according to the current profile of the PMSM and generates a first output voltage to power the magnetic bearing system in a second operating mode different from the first operating mode. A value of the first output voltage is generated based on the estimated rotation speed of the PMSM.

Abstract: An energy-saving control method includes obtaining a demand instruction configured to indicate an energy-saving operation and a performing time slot of the energy-saving operation. The energy-saving operation is determined based on load data of a power grid and is configured to reduce a load of the power grid. The method further includes transmitting a first control message configured to control an authorized device to perform the energy-saving operation in response to detecting that time reaches the performing time slot, and transmitting a second control message configured to control the authorized device to stop performing the energy-saving operation in response to detecting that time is outside the performing time slot.

Abstract: A laundry washing machine and method automate the selection of various operational settings for a wash cycle based in part on color composition data collected from a load of articles using a color detection sensor. In some instances, the capture of color composition data is triggered by detected weight changes sensed by a weight sensor as the load of articles is added to a wash tub, and is based in part on the detection of a stable weight in the wash tub for at least a predetermined duration. In addition, in some instances, color compensation data may be used to characterize a load of articles based in part on a color decision algorithm that assigns pixels in the color compensation data to different color categories.

Abstract: A latching structure, a household appliance and a control method for the household appliance are provided. The latching structure has a snapping member, a bracket, a limiting member, and a driving assembly. The snapping member is mounted on a door body and has a hook. The bracket is mounted on a housing and has a limiting portion. The hook can penetrate the bracket. The door body is connected to the housing in an openable and closable manner. The limiting member is rotatably mounted to the bracket and can reciprocate between an unlocked position and a locked position. The driving assembly is configured to engage with or disengage from the limiting member. In the unlocked position, the limiting member avoids the hook, and in the locked position, the limiting member is suitable for fitting the hook to limit a position of the hook.

Abstract: Provided are a heating sheet, a heating tube, and an electric appliance. The heating sheet includes a graphite sheet substrate. The graphite sheet substrate includes a heating region and a buffer region. The buffer region is located at two ends of the graphite sheet substrate. The heating region is connected to the buffer region, and located on a side of the buffer region facing away from the two ends. The heating region includes a hollow zone. A duty ratio of the buffer region is greater than a duty ratio of the heating region. The heating sheet has advantages of good impact resistance and strong anti-fracture performance.

Abstract: A recreational vehicle air conditioning system supports multiple recreational vehicle air conditioning units having closed air conditioning circuits and a controller that is electronically coupled to each of the recreational vehicle air conditioning units to control each of the closed air conditioning circuits to regulate an overall power consumption of the multiple recreational vehicle air conditioning units. A recreational vehicle air conditioning system may also support multiple recreational vehicle air conditioning units where a refrigerant line set is coupled between the recreational vehicle air conditioning units such that a compressor in one of the recreational vehicle air conditioning units is capable of supplying refrigerant to the evaporators of the multiple recreational vehicle air conditioning units, and such that valves coupled in series with each of the evaporators may be regulated to control cooling by each recreational vehicle air conditioning unit.

Abstract: The present disclosure provides a microwave cooking apparatus, a control method, and a storage medium. The microwave cooking apparatus comprises: a housing capable of enclosing a heating chamber therein; a solid microwave source disposed on the housing and used for emitting a first variable-power microwave; an antenna connected to the solid microwave source and used for feeding the first variable-power microwave into the heating chamber; and a controller connected to the solid microwave source and used for controlling the solid microwave source to operate and adjusting the first variable-power microwave. According to the technical solution of the present disclosure, on one hand, a better heating effect is able to be achieved for sealed foods, and on the other hand, a better unfreezing effect is also able to be achieved because the power of a solid microwave source is much lower than that of a magnetron so that during an unfreezing operation, foods to be defrosted will not be locally cooked resulting from local overheating caused when the foods to be defrosted locally absorbs too much heat due to excessive power.
