Depth of anaesthesia control investigation using robust deadbeat control technique

This paper investigates the depth of anaesthesia (DoA) control system using robust deadbeat technique. We propose to apply deadbeat control technique and develop a robust controller. The proposed robust control system with a deadbeat controller is evaluated in simulation. The performance is compared with that of a traditional control system with a PID controller and a control system with an internal model (IMC) controller. The results show that the proposed scheme has about 15% less overshoot, shorter settling time (about 1.5 minutes shorter) and more robust to disturbances caused by parameter changes. In addition, the proposed method is easy to design and impalement.
