Embodiment Construction

[0019] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0020] figure 1 It is a schematic flow chart of the first embodiment of the fuzzy control method of the present invention, as figure 1 As shown, the fuzzy control method of the present embodiment includes:

[0021] Step 101: Receive the detection input quantity sent by the detection device, and map the deviation value between the detection input quantity and the set value onto the input universe to obtain the fuzzy input quantity.

[0022] After the fuzzy controller in this embodiment receives the detection input sent by the detection device, it compares the detection input with a set value to obtain a deviation value; wherein the set value is equivalent to a control target value of the control system. The fuzzy controller performs fuzzy processing on the deviation value obtained above, and maps it to the correspondi...

Abstract

The invention discloses a fuzzy control method and a fuzzy controller, wherein the fuzzy control method comprises the following steps: receiving detection input quantity input by a detection device, and mapping a deviation value of the detection input quantity and a set value to an input discourse domain to obtain fuzzy input quantity; performing fuzzy reasoning and fuzzy decision according to the fuzzy input quantity to obtain fuzzy control output quantity of a corresponding output discourse domain; and converting the fuzzy control output quantity into control output quantity, outputting the control output quantity to an actuating mechanism, and controlling the controlled object by the actuating mechanism according to the control output quantity. Through fuzzy control method and the fuzzy controller, the chlorination in a water plant can reach optimal control effect.

Description

technical field [0001] The invention relates to the field of fuzzy control, in particular to a fuzzy control method and a fuzzy controller. Background technique [0002] The application of control technology is very extensive. For example, chlorine has been used as the main disinfectant in drinking water disinfection for a long time in my country. In the process of drinking water disinfection, the amount of chlorine added needs to be controlled. On the one hand, ammonia nitrogen, odor and pathogenic microorganisms can be removed by adding chlorine to the water, and the growth of algae in sedimentation tanks and filters can be controlled; on the other hand, residual chlorine can be kept in the water distribution network to prevent Microbes re-grow, so chlorination is a key link in the routine water treatment process of water plants. When the process conditions are constant, the dosage of chlorine directly affects the disinfection results. Realize the chlorination process wi...
