Novel Multiple Time Scale Adaptive Control for Uncertain Nonlinear Dynamical Systems
Abstract
The purpose of this action is to add a FY23 funding increment in the amount of $199,010.00 for a new Grant, GRANT#13711192. Approved for Public Release. Many naval aerospace systems such as unmanned air vehicles, high performance aircraft and satellites are multiple time scale (MTS) systems. MTS systems are particularly interesting from a controls perspective because the time scale separation in the plant can cause degraded performance or even instability under traditional control methods. Accounting for the time scales can remedy this problem. For example, a MTS control technique demonstrated significantly reduced rise times over traditional Nonlinear Dynamic Inversion (NDI). Similarly, traditional adaptive control has been demonstrated to have reduced performance on MTS systems. On the other hand, traditional control techniques that are specifically designed for MTS systems cannot account for systems with model uncertainties cite{saha_2018}. Thus, a method of MTS control for uncertain systems is needed. For this purpose, a novel methodology, called [K]Control of Adaptive MTS Systems (KAMS), is proposed herein. KAMS expands the class of dynamical systems to which MTS control and adaptive control can apply. While other research uses elements of adaptive control and MTS control, other research stops short of fully and rigorously combining them. Compared to this other research, KAMS offers improved performance, increasedrobustness, easier implementation, generality, and insight into the physics of the system.
