Intelligent speed control device and dehumidifying fan system

Abstract

A smart speed control device includes a sensing unit, a processing unit, and a storage unit. The storage unit stores a speed control model and a feedback lookup table. The speed control model determines an adjustment strategy corresponding to a target state based on environmental values. The processing unit inputs the environmental values ​​as the current state into the speed control model to obtain the adjustment strategy and generates proportional-integral parameters and control signals based on the adjustment strategy. After one control cycle, the processing unit generates the adjusted state and a reward value based on the adjusted state, and updates the feedback lookup table based on the adjusted state and the reward value. By controlling the fan equipment and training the speed control model based on environmental values, the processing unit enables the fan equipment to adjust its operation in real time according to the environment, solving the problem of energy waste.
