Study of Home System Based on Intelligent Control Technology

Home system is a complex multivariable system. It is nonlinear time-varying. And dynamic coupling relationship exits among variables. It is hard to found accurate system equations. The paper takes PLC control technology joining with particle swarm optimization (PSO) based on average velocity fuzzy PID algorithm, adopts power line carrier as networking technique, and uses configuration technology, to force home intelligent control. Experiments show that the household temperature acts stably and the environment feels comfortable through actions like dynamically window ventilated, curtain dimmer started and air-conditioning opened according to the real-time environment. Moreover configuration interface operation is easy, and online modification is convenient. Therefore it owns a good popularization value.
