Optimized Control Strategies for Tremor Suppression and Voluntary Motion Tracking: A Simulation Study

Tremor is characterized as an oscillatory, rhythmic and involuntary movement of a body component [1] and is among the most prevalent disorders among the adult population [2]. Tremors are one of the most crippling signs of Parkinson's disease (PD), a progressive neurological illness that is characterized by a range of motor and non-motor functions. Although tremor is not a life-threatening condition, it can cause social discomfort, dependence and functional impairment. Over 65% of the people with upper limb tremor experience significant challenges carrying out activities of daily living. As per the recent research, individuals over 65 years who experience essential tremors account for up to 5% of the population, while those who experience Parkinson tremors account for up to 1%. Extremely high tremor intensities frequently result in complete impairment for the afflicted individual [3].
