摘要：A new DREM-based (Dynamic Regressor Extension and Mixing) modification for output adaptive controller with input multi-harmonic disturbance cancellation is proposed in this paper. This approach provides monotonic convergence of the disturbance internal model parameters’ estimates to its true values. We also introduce a novel algorithm for the DREM-based estimator gains tuning in order to improve convergence under poor excitation. Parallel kinematics Ball-and-Plate robotic system is considered as a test-bed, while the non-prehensile ball stabilization in a predefined coordinates under bounded disturbances is a task to be solved.
