Abstract

The invention discloses a fluid mixing control system based on a double-closed-loop PID algorithm, which includes a microcontroller module, a power management module, a management control module, an output drive module, and an output feedback module; the microcontroller modules are respectively connected to the power management module , a management control module, an output drive module, and an output feedback module. The fluid mixing control system based on the double-closed-loop PID algorithm of the present invention proposes a double-closed-loop PID algorithm, which can solve the problem that it is difficult to control the temperature of the indoor bathroom due to poor timeliness of algorithm feedback.

Description

technical field [0001] The invention relates to fluid mixing control, in particular to a fluid mixing control system based on a double-closed-loop PID algorithm. Background technique [0002] At present, the traditional bathroom control uses manual proportional mixing or measures the temperature of cold and hot water before mixing according to the temperature sensor and then performs proportional mixing. Afterwards, the water temperature is difficult to recover automatically and must be readjusted, which seriously affects the user experience. [0003] The negative feedback hybrid control system based on the PID algorithm model is very significant in the field of industrial control, but due to the complexity of the algorithm model, the complexity of the algorithm model is high and the timeliness of feedback is poor, it cannot be applied to the field of home bathroom control. [0004] And the traditional fluid temperature closed-loop PID algorithm only detects the temperature...
