Design of fuzzy controller for air-conditioning systems based-on semi-tensor product

A novel air-conditioning fuzzy controller based-on semi-tensor product (STP) is applied into a thermal comfort control system, according to difficulty for air conditioning to control indoor thermal comfort. Through STP of matrices, the measured sampling data of indoor temperature and humidity are used to obtain a matrix-based fuzzy relation structure model. Instead of the complex process of logical reasoning and fuzzy rule sets, the matrix algebraic form is constructed directly and the design of air-conditioning comfort control systems based-on indoor temperature and humidity is realized. Then this air-conditioning fuzzy controller is applied into an indoor thermal comfort control system. Experiments and simulation results shown that this air-conditioning fuzzy controller can work well with following indoor thermal comfort. This fuzzy controller based-on fuzzy relation matrix is particularly suitable to non-decomposable multi-output nonlinear systems.
