Paper Abstract

Hyperthermia is one of the effective methods to treat the bladder cancer. In the process of bladder cancer hyperthermia, the precise measurement and control of the temperature on tumor is one of the critical technologies for medical instruments. In order to achieve precise control of the temperature, the author incorporates the grey forecasting, fuzzy control and conventional PID control. In this article the author presents the fuzzy PID control strategy based on grey forecasting. That control strategy can be divided into three steps: firstly, build the fuzzy tuning rules by simulation and analysis and obtain the parameters of PID controller by reasoning, secondly, determine the control effect directly through the PID control law, and then put the grey forecasting into use online. Simulation results show that the strategy combining grey forecasting with fuzzy control is superior to fuzzy PID control. It has strong robustness and self-adaptive ability.
