Embodiment Construction

[0056] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0057] Such as figure 1 Shown, the room temperature control algorithm based on fuzzy neural network of the present invention, main content is as follows:

[0058] 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 consta...

Abstract

The invention discloses a room temperature control algorithm based on a fuzzy neural network. A double-input single-output fuzzy neural network controller is designed, the room temperature is detected in real time and output and a temperature setting value are tracked, and an online learning mechanism is adopted to adjust adjustable parameters in the controller in real time to enable the controller to adapt to the change of room temperature and track the temperature setting value. Learning and computing functions of a neural network are integrated into a fuzzy system, and the human-like IF-Then rule of the fuzzy system is embedded into the neural network, so that the adaptive ability of a fuzzy control system is improved on the premise of maintaining the strong ability of knowledge expression, and the system has the ability of self-learning.

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...
