A Control System of Indoor Air Quality Based on Modified Smith Predictor
Although the research of indoor air quality control is a hotspot in recent years, because of the non-liner, time-varying, complex systems of indoor environment, it’s difficult to use conventional methods to obtain satisfactory control performance. In this paper, based on the control characteristics of indoor environment, a modified Smith Predictor was proposed, and several key issues of system implement were discussed. Also, the filters with Smith predictor control were proposed based on the conventional PID controller. Thus, the structure of the controller was constructed for complex system. Through Matlab simulation analysis, it showed that the predicted control system with Smith-band filter has a better robustness on the model error, and the indoor environmental parameters was effectively controlled.
