9350268 Garcia The focus of Dr. Ephrahim Garcia's research, during his tenure as a Presidential Faculty Fellow, is on the control of flexible dynamic systems. Actuation of electro-mechanical devices is used to control the dynamic behavior of systems such as automobiles, robotic manipulators, bridges and aircrafts. However, the dynamics of the structure and the actuator are often coupled leading to structural instability. Collocated feedback strategies are used to avoid instability phenomena. In addition, smart or adaptive structures are used for structural control and health monitoring. Smart structures technology incorporates an integration of sensors, actuators and structural members to insure stability, structural identification and vibration suppression. Application of neural networks is included for structural self diagnosis and control. *** v s t $ $ ( F / ` ` 1 Times Symbol " Helvetica 5 Courier New ` , , , - " h c % c % c % v \ I R:\WW20USER\ABSTRACT.DOT abgarcia maryjohnson maryjohnson

9350268加西亚（Garcia）在担任总统教职员工任职期间，埃弗拉希姆·加西亚（Ephrahim Garcia）博士的研究重点是控制灵活的动态系统。电力机械设备的致动用于控制汽车，机器人操纵器，桥梁和飞机等系统的动态行为。但是，结构和执行器的动力学通常是耦合导致结构不稳定性的。并列的反馈策略用于避免不稳定现象。此外，智能或自适应结构用于结构控制和健康监测。智能结构技术结合了传感器，执行器和结构成员的整合，以确保稳定性，结构识别和振动抑制。神经网络的应用包括用于结构自我诊断和控制。 *** v s t $ $（f /``1次符号“ Helvetica” 5 courier new n n n n n n'，， - ” H C％C％C％V \ I R：\ WW20USER \ ww20user \ abractive.dot Abgarcia Maryjohnson Maryjohnson Maryjohnson
