Abstract

The actuator dynamics of an active load alleviation system is investigated. For the design of the control law a model, consisting of aerodynamics, structural dynamics and actuator dynamics is required. Whereas methods for modeling of aerodynamics and structural dynamics exist, an equivalent model for the actuator must be determined experimentally. A nonlinear actuator model is derived and identified. The impact of nonlinearities on the control perfomance is quantified with simulations.
