In this paper, a new approach to identify the parameters of robot manipulator dynamics is presented. The approach is based on exciting the robot manipulator with multiple identification trajectories that pass through the operating point with specific speeds and accelerations. The position, velocity and acceleration of the robot joints along with the corresponding torque at the operating point are...
In this study, adaptive tracking control (ATC) is presented for a toggle mechanism of electric injection molding machines in the presence of uncertainties and disturbances during closing operations. The controls are developed based on mathematical knowledge of the toggle mechanism and the permanent magnet synchronous motor (PMSM). The proposed controls are robust not only to parametric uncertainties...
Dynamic parameters of a robot affect the performance of advanced control schemes significantly. In this study experiments to identify the dynamic parameters of AT2 robot are carried out. The excitation trajectory for identification is parameterized with Fourier series. The trajectory is optimized to minimize effects of uncertainty using condition number as the index. Recursive optimization is proposed...
The task of solving the adaptive control of a partially and imprecisely modeled electrical vehicle driven by three omnidirectional wheels together with the torque and/or power limits of their electric driving motors is considered. The vehicle is very roughly modeled as a rigid body while the a part of the burden carried by it through elastic connection is completely neglected in the controller's model...
