Abstract: Regarding realisation of an AP, specifically for the optimal management of concentration of blood glucose (BG) with an appropriate feedback mechanism has great significance for Type-I diabetes mellitus (TIDM) patients since past few decades. The AP with an efficient control approach algorithm for regulating various continuing clinical illnesses, which are dependent on prolonged drugs, is now extremely essential besides the BG control. In the current effort, a brand-new SMC/SHP has been proposed to address the aforementioned issue. A patient with TIDM and AP in a 9th-order state space model is taken into consideration for constructing the SMC/SHP. To enhance control performance, the conventional sliding mode control (CSMC) is reformulated in this control method using a sliding hyperplane parameter basing on the whole state feedback technique. By comparing the results with other previously published control methodologies, comparative result analysis serves as evidence for the justification of SMC/SHP's improved control performance. The simulations are run in the environment of MATLAB/SIMULINK and the results indicate that the suggested approach has relatively higher ability to manage concentration of BG within the normo-glycaemic range in terms of robustness, accuracy, rapid damping and stability.
