Abstract

Aimed at the optimization of sensors’ numbers and locations in helicopter active control of structural response (ACSR), a set of optimization selection method is brought out. This method can effectively reduce numbers of sensors and find their relevant optimization locations, and at the same time the effect of vibration reduction is almost no loss. So the control scale of hardware can be reduced distinctly. The optimization problem is resolved with the genetic algorithm. Taking the Z11 light helicopter as an example, the effectiveness of the method is validated. The results show that using this optimization method, the best collocation scheme of sensors in ACSR can be achieved, with fewest sensors and good effect of vibration reduction in whole observed locations
