US Application 63/364,580 Dated May 12, 2022, "Fast Non-Ringing Dynamic System Transient"
WO 2023/220669 Published 16 November 2023, "Fast Non-Ringing Dynamic System Transient"
Abstract: A method of control avoids inducing undesired oscillations, harmonics, and ringing during the energization or de-energization of a dynamic system. The same control method can deliberately induce desired oscillations, harmonics, or ringing during the energization or de-energization transients of a dynamic system. The control method accounts for energy inflows and outflows. The free response of the dynamic system is not affected but the forcing function that stimulates the dynamic system can be exactly tailored to suit the desired response throughout the entire duration fo each transient response. Continuous control over the forcing function yields continuous control over the transient response, where undesired dynamics are not stimulated instead of being suppressed.
