空调房间温度复合模糊控制器研究

Research of Compound Fuzzy Controller in Temperature of Air-conditioning System

结合空调房间温度控制具有大滞后、非线性、时变的特点,设计了一种比例-模糊PID控制器。建立了空调温度的系统的模型,介绍了控制器实现原理以及结构,并详细叙述了各个参数的模糊控制规则。在MATLAB的Simulink中搭建系统模型并与传统PID比较,最后进行仿真。仿真结果表明,所设计的比例-模糊控制器比传统PID控制器有更好的动态性能和稳态性能。

Combined with characteristics of large time delay, nonlinear, time-varying on air-conditioned room temperature control, designing a proportion - fuzzy PID controller, establishing air-conditioning temperature system model, introducing controller principle and structure, describing various parameters of the fuzzy control rules in detail. The system model was built and compared with the traditional PID in Simulink of MATLAB, and finally making simulation. Simulation results show that the proportion-fuzzy controller has better dynamic and steady performance than conventional PID controller.
