Current models for adaptive control have low accuracy
Adaptive control is a method for controlling vehicles that is used when parameters are uncertain or are expected to change. Research in this area aims to reduce modeling error while maintaining robustness and improving performance. Output feedback adaptive controllers are specifically used when it is not possible to see the entire state of a process such as (insert example here). The current models on the market account for active control of noise, vibrations, flows, and combustion, but these processes tend to have low accuracy.
New innovation improves adaptation while also having simpler architecture
Researchers at Georgia Institute of Technology have developed a new output feedback adaptive control architecture that is far less complex than existing architectures while also improving stabilization and adaptation. Specifically, this model generalizes the assumption of constant unknown ideal weights to the existence of time-varying weights. This adds memory to the adaptive law, which improves transient behavior while also maintaining adaptability.
This invention is an output feedback adaptive control model for vehicles designed to work in a system where parameters are unknown or may vary. The architecture of this novel method is simpler than others of its kind while also improving adaptive control stabilization and tracking performance.
