Abstract

People with disabilities such as Parkinson's, Holmess or other disease have difficulty operating conventional joysticks because of the tremor. This paper will present a study of the joystick control for the minimization of this tremor. For this minimization, different types filter and control were study and compared. These controls were tested in a wheelchair laboratory to see the behavior of the wheelchair with diferents inputs. Simulation results were presented to show the tremor cancel as well as the performance of the control development. With this results is possible to develop new products for people with special needs and to develop better controls for people with tremor hand.
