super twisting sliding mode controller for parkinson's tremor rehabilitation

Deep brain stimulation (dbs) has been a prominent therapy option in recent years for movement disorders, namely hand tremor in individuals with severe parkinson's disease (pd). a common method for figuring out parkinson's patients' tremor is to use a closed-loop control system for deep brain stimulation (dbs) that includes a basal ganglia (bg) model. this study shows how to effectively control two parts of the basal ganglia (bg) at the same time: the subthalamic nucleus (stn) and the globus pallidus internal (gpi). this can help reduce parkinson's tremor and the amount of stimulation that is needed. the use of this particular method yields a decrease in the magnitude of the applied field and mitigates the adverse consequences arising from the intensity of stimulation. the implementation of a super twisting sliding mode controller (stsmc) results in the stimulation of stn, while a partial state feedback (psf)controller controls gpi. the simulation results pertaining to the stimulation of two locations inside the basal ganglia demonstrated a commendable level of performance. the simulation findings provide empirical evidence to support the claim that the suggested strategy is superior and more effective when compared to sliding mode control
