摘要: Abstract In this paper, a nonlinear active damping strategy based on force feedback is proposed. The proposed device composed of pair collocated actuator and sensor. control law formed by feeding back the output sensor, through one single, double integrator another its cube. An equivalent mechanical network which consists dashpot, an inerter cube root developed to enable straightforward interpretation physics behind. Closed-form expressions for optimal gains are derived. Numerical validations performed demonstrate strategy.
