Novel Hall-sensor Joystick Based on Nonlinear Compensation
A non-contact electronic joystick using a single hall-sensor is newly designed, which detects a horizontal vector in the magnetic field. Furthermore, in this paper, the nonlinear character between the output of the hall-sensor and the movement of joystick bar is illustrated. The dynamic horizontal vector of the magnetic flux is detected by the hall-sensor while a permanent magnet is rotated with the joystick bar, which has a two-dimensional detecting area. Using the nonlinear adjustment equations, the output signals of the hall-sensor have been linearized to give higher accuracy in two-dimensional movement. Finally, through real experiments, it is shown that the single hall-sensor structure mechanism is superior to the dual sensor structure in sensing two-dimensional motion without offset.
