The intelligent switch refers to the unit that uses the combination and programming of the control board and the electronic components to realize the intelligent switch control of the circuit. Switch control, also known as BANG-BANG control, is used in many household appliances and lighting fixtures due to its simplicity and ease of implementation. However, the conventional switch control is difficult to meet the requirements for further improvement of control accuracy and energy saving.
The conventional switch control mode has only two control states in the control cycle, and is either switched on, is a fixed constant value, or is off, and the control amount is zero. This kind of fixed control mode lacks the characteristics of manual switch control. In the process of manual switch control, a person needs to select different switch control strategies according to the error and the trend of error change. For example, in a control period T, the output time of the control amount can be adjusted as needed. Based on human knowledge and experience, based on the actual error variation law and the inertia of the controlled object (or process), pure lag and disturbance characteristics, the switch control that selects different control strategies according to a certain mode is called intelligent switch control. .
