Optimal Shape Control of Piezoelectric Intelligent Structure Based on Genetic Algorithm

Optimal Shape Control of Piezoelectric Intelligent Structure Based on Genetic Algorithm

Shape variation induced by mismachining tolerance, humidity and temperature of the working environment, material wear and aging, and unknown external load disturbances have a relatively large influence on the dynamic shape of a mechanical structure. When integrating piezoelectric elements into the m...
