Research and Application of Self-Adaptive Fuzzy Control in the Negative Pressure Isolation Ward Control System

In this paper, aimed at the negative pressure isolation ward with the characteristics of multiple variables, strong coupling and instability, according to the research of latest isolation environmental air current structure and based on the conventional PID control, this paper uses fuzzy inference to achieve the parameters of PID on-line adaptive setting, so that the control of negative pressure isolation ward can achieve the satisfactory control.
