Using PID fuzzy control technology and advanced digital technology, a fuzzy control is formed by combining Pvar, Ivar, Dvar, and COMSensTM to solve the problem of inertia temperature error; It can automatically monitor and adjust the temperature, thereby maintaining the stability and suitability of the environmental temperature. It has the characteristics of high precision, automation, efficiency, and reliability, and is widely used in industrial, medical, and daily life fields, becoming an indispensable technology for modern production and life.
