From modern control theory, a close loop system of novel V/F converter based on Z-elements is presented and it lay special stress on discussing how to solve temperature drift in the system with feedback control principle. At the same time, a reliable method is given that can be used in actual produce process. Because of its advantages such as simply circuit, cheap cost, high precision and low power consumption and so on, the system can alter traditional A/D converter as an interface between analogue sensors and digital computers.Key Words: V/F converter; Z-elements; temperature drift
