Embodiment Construction

[0058] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0059] like figure 1 Shown, the room temperature control algorithm based on fuzzy neural network of the present invention, main content is as follows:

[0060] Design a dual-input and single-output fuzzy neural network controller, through real-time detection of room temperature tracking output and temperature setting value, combined with online learning mechanism to adjust the adjustable parameters in the controller in real time, so as to adapt to room temperature changes and track temperature setting value. In the figure, u(t) represents the control amount, where du / dt represents the function of the backward shift operator, that is, to obtain u(t-1), the control amount at the previous moment. FNN stands for Fuzzy Neural Network Controller. K represents the proportional coefficient of the fuzzy neural network controller, which is constantl...

Abstract

The invention discloses a room temperature control algorithm based on a fuzzy neural network. A fuzzy neural network controller with dual input and single output is designed. By detecting the room temperature tracking output and temperature setting value in real time, combined with an online learning mechanism, the controller can be adjusted in real time. Adjustable parameters to adapt to room temperature changes and track temperature setpoints. The invention integrates the learning and computing functions of the neural network into the fuzzy system, and embeds the human-like IF-Then rules of the fuzzy system into the neural network. Self-learning ability.

Description

technical field [0001] The invention relates to a room temperature control algorithm based on a fuzzy neural network, which belongs to the field of automatic control of air conditioners. Background technique [0002] The air-conditioning room system is a complex control object with nonlinear, large time-delay, strong coupling and time-varying characteristics, and is also subject to many uncertainties, such as the flow of people in the room, the heating of various electrical equipment, and the opening and closing of doors and windows Wait. [0003] At present, PID control is widely used because of its simple principle, strong applicability and strong robustness. However, PID performs poorly in controlling complex processes with nonlinear, time-varying, coupled, and uncertain parameters and mechanisms. [0004] Intelligent control has the ability of self-learning and self-adaptation, and has good control effects on linear and nonlinear systems, and can well solve the control...
