As well known, process identification is very important in process control. A Open-loop identification method is proposed in this paper. The identification object is a simulated facility with constant temperature hyperthermic perfusion treatment on bladder cancer. Open-loop step response is applied ,the process input and the resulted output response are logged, and the improved area method is adopted, from which the parameters of a first-order plus dead-time model can be estimated. Based on some PID tuning rule the closed loop experiments have been conducted. The experimental results have shown that the proposed method has good identification accuracy and is insensitive to the noise. Furthermore, the experiments of the closed loop control system have also indicated the design closed loop control system is valid.
