In this paper, we proposed a disturbance rejection control method to improve the position keeping accuracy of an underwater robot. Not like a ground robot, the controlling of a floating body is a critical requirement to acquire high quality sensor data from, for examples, a gyro, an underwater optical camera, and an imaging sonar. The proposed controller consists of a model-based robust compensator...
In the traditional positioning system of the overhead crane, the method used is low positioning accuracy and ineffectiveness. In this paper, a novel positioning system is presented, which is a new positioning control system using laser range finders and bar code positioning system (BPS) to locate an overhead crane. The actual application shows that novel positioning control system is more than 200...
