چکیده :

The current paper investigates the blood glucose level in the presence of a sensor fault. To this aim, the eligibility trace algorithm, as a Reinforcement Learning (RL) method, is employed. Here, a soft and abrupt fault is applied to the system and a time window concept detects the fault type. At each time step, a feedforward neural network monitors the amplitude and type of the applied fault as these can affect the injected dosage. In order to comprehensively investigate the performance of the eligibility trace algorithm on the blood glucose level control in diabetic patients, the present study compares the proposed method with another featuring a combination of the eligibility trace algorithm and a sliding mode control. Finally, it is demonstrated that, with a lower dosage, the eligibility trace algorithm is able to control the blood glucose level in the presence of a sensor fault and so attain the desired level. More importantly, in the proposed method, the controller design is much easier in comparison with the combination of the eligibility trace algorithm and the sliding mode control.
