    The webinar talk presents a practical motion controller design technique for precision positioning devices including strain wave gearing, e.g. industrial multi-axis robots, precision rotation stages, etc. Since HarmonicDrive® gears (HDGs), a typical strain wave gearing, inherently possess nonlinear properties known as Angular Transmission Errors (ATEs) due to structural errors and flexibility in the mechanisms, the ideal positioning accuracy corresponding to the apparent resolution cannot be essentially attained at the output of gearing in the devices. In addition, mechanisms with HDGs generally excite resonant vibrations due to the periodical disturbance by ATEs, especially in the condition that the frequency of synchronous components of ATE corresponds to the critical mechanical resonant frequency. The seminar, therefore, focuses on the accurate settling and vibration suppression in positioning, in order to improve the performance deteriorations by applying model-based feedforward and feedback control approaches. In the compensator design, under the assumption that the accurate mathematical models for ATE can be obtained, a model-based feedforward compensation has been introduced to improve the settling performance in the load position, as well as a feedback compensator with a variable notch filter has been adopted to achieve the mechanical vibration due to the ATE effects. The proposed approaches have been applied to precision motion control of actual devices as servo actuators, and verified through numerical simulations and experiments.
