Designing of Adaptive Model‐Free Controller Based on Output Error and Feedback Linearization

Abstract and Applied Analysis, Volume 2013, Issue 1, 2013., 2013
This paper introduces a new approach to design Model‐Free Adaptive Controller (MFAC) using adaptive fuzzy procedure as a feedback linearization based on output error. The basic idea is to transfer the control signal to an appropriate surface and then, depending on the output error of system, the control signal changes around this surface. Some examples

DNA nanomachine‐driven chemodynamic therapy against glioblastoma

Aggregate, Volume 5, Issue 6, December 2024.
A novel DNA nanomachine (Cu@tFNAs‐G‐A NM) is constructed and exhibits the ability to effectively penetrate the BBB and selectively accumulate in tumor cells. Moreover, the Cu@tFNAs‐G‐A NM can react with tumor‐overexpressed GSH and H2O2 to generate a large amount of •OH, thus leading to an effective CDT against GBM.
