Abstract
The first resonance mode of mechanical systems is a significant limit to the achievable positioning bandwidth. This resonance is dependent on the physical, material and geometric properties of the system. Significant effort is typically required to increase the resonance frequency by increasing stiffness or reducing mass. In this article, a modified IRC scheme is presented that effectively shifts the first resonance mode to a higher frequency, thereby enabling a substantially higher positioning bandwidth. A 70% increase in positioning bandwidth is demonstrated.
