The aim of this paper is to test the usefulness of a new approach based on partial feedback linearization to control the Pendubot. The control problem stated in the article is to stabilize the Pendubot in the upright position. In particular, properties of the closed-loop system and the zero dynamics are investigated and illustrated by results of simulations. Next, the performance of a hybrid-like controller in the case of input saturation is evaluated by conduction extensive simulation trails. The experimental results suggest that the considered control methodology can be successfully applied for a real system.
This paper presents a solution for universal multidrive control system, which can be used as a base for the rapid prototyping of various kinematic structures, particularly in robotics, for multiple-axis synchronization tasks, or as a test bed for verification of modern control algorithms for electric drives. The example of the practical application of the proposed system was also given: It was used during prototyping process of a quadruped walking robot, powered by multiple electric motors. The abilities and performance of the system were verified with the attempt to realize the dynamic gait of the robot.
The aim of this paper is to verify whether the well known control algorithms for double inverted pendulum could be used for stabilization of the Acrobot after impact. Both methods utilize feedback linearization techniques. The first control algorithm is based on careful selection of output function that leads to a proper relative degree of the system. The second approach makes use of system's kinetic symmetry property with backstepping procedure.
