In this paper active vibration control (AVC) methodology is presented by the author using self-sensing magnetic transducers for a flexible plate structure. H_∞ Optimized positive position feedback (HOPPF) controller is tested and verified for multi-modes multi-input-multi-output (MIMO) vibration suppression through simulation and experiment implement. Genetic algorithm (GA) searching is applied to obtain the optimal parameters of the controllers according to the minimization criterion solution to the H_∞ norm of the whole closed-loop system.

Objectives and Key Themes
This paper investigates the application of active vibration control (AVC) using self-sensing magnetic transducers to mitigate vibrations in a flexible plate structure. The study focuses on implementing and validating a H∞ Optimized Positive Position Feedback (HOPPF) controller for multi-mode, multi-input-multi-output (MIMO) vibration suppression using both simulation and experimental methods. Genetic Algorithm (GA) optimization is employed to determine optimal controller parameters based on minimizing the H∞ norm of the closed-loop system.

Chapter Summaries
The paper begins by introducing the challenges of unwanted vibration in lightweight structures and outlines the need for vibration control methods. It then presents an overview of existing vibration control techniques, including modal control, independent modal space control (IMSC), resonant control, and Positive Position Feedback (PPF).
