This study suggests a position estimator using linear hall effect sensors and iterative algorithm. Compared to other typical position sensors such as encoders and resolvers, hall effect sensors have several advantages. (e.g., insensitivity to both external disturbances and environmental contaminations, and having a scaleless property). Furthermore, linear hall sensors provide more detailed information...
This paper proposes a new scaleless position estimation method. From the industrial perspective, the Hall sensor has several advantages: tiny size, light weight, extremely low cost, and insensitivity to environmental contamination and external disturbance. Compared to the square wave Hall sensor, the linear Hall sensor provides more detailed information along the position. However, for combining more...
Linear motor system has been developed to achieve high speed and high precision motion control in linear motion system, since rotary type motor has backlash and hysteresis due to mechanical parts like chain, belt or screw. However, paradoxically, linear motor system becomes more sensitive to the external disturbance, because it doesn't have such transmission mechanism. Many studies have been focused...
