tropospheric error modeling for gps positioning
in this paper a practical method for tropospheric effects on gps derived coordinates in absolute mode is presented. gps observations at the permanent gps stations can be used as source of information for the modeling. the developed model is a time-dependent model and as such differs from usual tropospheric models, which are based on atmospheric parameters, i.e. temperature, pressure and humidit...
متن کاملModeling, Control and Simulation of Cascade Control Servo System for one Axis Gimbal Mechanism
The gimbal stabilization mechanism is used to provide the stability to an object mounted on the gimbal by isolating it from the base angular motion and vibration. The purpose of this paper is to present a model of control servo system for one axis gimbal mechanism using a cascade PID controller. The gimbal torque relationships are derived by taking into consideration the base angular motion. Th...
متن کاملRobust Machine Tool Thermal Error Modeling Through Thermal Mode Concept
Thermal errors are among the most significant contributors to machine tool errors. Successful reduction in thermal errors has been realized through thermal error compensation techniques in the past few decades. The effectiveness of thermal error models directly determines the compensation results. Most of the current thermal error modeling methods are empirical and highly rely on the collected ...
متن کاملError Modeling for Structural Deformations of Multi-axis System Based on Svr
Multi-axis system is constituted by the mechanical links, and the link position load deformations are nonlinear. That is an important factor to affect the positioning accuracy of multi-axis system. As the nonlinear characteristics of link position and load deformations, a novel method for modeling deformations of loaded components based on SVR was presented. The 2R manipulator load deformations...
متن کاملDigital Servo Calibration and Modeling
The introduction of digital microcontrollers into “hobby” servos opens new doors for consumer and educational robotics. However, the new operational modes, parameters, and sensory feedback also add complexity. This paper will analyze the capabilities of these servos, and describe methods of calibration and motion modeling for accurate planning and control. As much as possible, these methods avo...
