【Abstract】 An integrated optimal determination of collocated actuator/sensor location s and feedback gain is carried out by minimizing an energy criterion, which is c hosen as the integrated total energy stored in the system. A fast converging GA used in this optimization is proposed. The experimental results indicate the hig h efficiency of this optimal criterion and method. At the same time, The vibrati on of flexible plate is effectively suppressed by the closed loop active control system.更多还原
