The research and development to use wood ceramics (WCM) as a new type gas sensor is being carried out. In the experiment, the temperature of WCM must be controlled on the desired value in order to measure a change of the electric resistance of WCM to gas. However, it is very difficult to control from the several reasons ; the temperature falls sharply because the temperature of gas is low, the size of WCM isn't always the same, and the physical constants of the thermal conductivity, density and specific heat cannot be obtained correctly, these values depend on the temperature when WCM is made. Therefore, a robust control law is necessary to overcome these disturbances and uncertainties. This author showed that sliding mode controller was effective in the past to control the temperature of processes with uncertainties. This paper applies a sliding mode controller for the temperature control of WCM. Cascade control, the algorithm of fictitious set point, and the new estimation of disturbances are added to the usual technique. The experimental results show that fixed temperature rise can be realized and that overshooting from the desired value can't occur.
