Hyperthermia therapy is one of the newest methods for tumor treatment in recent years.Based on the one-order inertia tache Smith predictor

aimed at the pure hysteresis characteristic of hyperthermia temperature the fuzzy Smith intelligent control method which combines the fuzzy PID control with the fuzzy adaptive Smith predictor is proposed.According to biology thermal conductivity equation

a hyperthermia treatment maths model is established.Simulation results show that the method can improve the qualities of control and enhance the robustness and stability of the temperature control system.
