Traditionally, the sensor design for Inertial Sensing of Human movement/posture is done using an accelerometer-gyroscope combination while detection of static or dynamic activities is done using uniaxial accelerometers. A single axis accelerometer-gyroscope combination uses sensor fusion along with a Kalman Filter to estimate the inclination. The inclination is obtained by integrating angular velocity...
Proportional-Integral-Derivative (PID) control has been most commonly used to operate mechanical systems. In PID control, however, there are limits to the accuracy of the resulting movement because of the influence of gravity, friction, and interaction of joints. In contrast, digital acceleration control (DAC) is robust against these modeling errors by nonlinear terms. DAC requires information of...
This paper focuses on the controller design of microgravity system on ground for the captured target of the free-flying space robot. The kinematics analysis of the collided static target and kinetic target are done. In vertical direction, the constant tension method is brought forward. The track of the objectpsilas deflexion angle and displacement in polar coordinate is proposed so that the moving...
