  • Closed-loop compensation for kinematic error in harmonic driver for precision control applications
    Patent number: 6459940
    Abstract: Nonlinear control algorithms to compensate for kinematic error in harmonic drives provide a solid basis to improve their performance of harmonic drives in precision positioning applications. The present closed loop control algorithms compensate for kinematic error irrespective of its form in both set-point and trajectory tracking applications.
