To overcome the limitations of the independent stacked hybrid actuator with multiple sensors, a new hybrid linear actuator combines the advantages of both technologies: piezo actuator for extremely high accuracy and motorized stage for long travel ranges. A hybrid linear actuator prototype has been developed for testing in our satellite tracking antenna pointing control system. For the maximum absolute positioning accuracy, host positioning controller depends only on one common position sensor for both the coarse and fine positioning at the same time. Synchronization control scheme shows promising results for extremely small steps, high repeatability and good linearity over long travel ranges.
