The invention relates to the technical field of compressors, in particular to a rotating speed control method and device, a controller, a compressor, a vehicle and a medium. The method comprises the following steps: acquiring a target rotating speed; and when the current rotating speed is smaller than or equal to the preset critical value, executing a first rotating speed control strategy according to rotor position information of the compressor and the target rotating speed. The rotating speed of the compressor can be accurately controlled according to the rotor position information at the low rotating speed section, the control efficiency and control precision of the compressor are improved, the compressor can be controlled to operate stably, meanwhile, the requirement of a user for the small refrigerating capacity is met, and the situation that the compressor cannot operate at the ultralow rotating speed, and consequently the refrigerating capacity is wasted is avoided.
本发明涉及压缩机技术领域,具体涉及一种转速控制方法、装置、控制器、压缩机、车辆及介质。所述方法包括:获取目标转速;在当前转速小于或等于预设临界值时,根据压缩机的转子位置信息以及目标转速执行第一转速控制策略。本发明在低转速段可以根据转子位置信息对压缩机转速实现精准控制,提升了压缩机控制效率和控制精度,可以控制压缩机稳定运行,同时满足了用户对于小制冷量的需求,避免了压缩机无法以超低转速运行所造成的冷量浪费。
