Description

technical field [0001] The invention belongs to the technical field of automatic control, and in particular relates to a vector ventilation control system and its establishment method and control method. Background technique [0002] With the development of automatic control, the traditional ventilation control system cannot meet the current requirements for automatic control and precise control. The emergence of vector control technology has become a hot spot in the development and research of automatic control and precise control at home and abroad in recent years. It is widely used in flight attitude control, asynchronous motor control and other fields. In the control of the actual ventilation system, more accurate control of the internal and external environment and avoiding the appearance of parameter steps caused by air flow have become an important direction and challenge for current ventilation control. [0003] Vector control is control with direction. For the cont...
