This paper examines the application of control systems for the alleviation of the vibratory loads transmitted to the airframe by the wing-proprotor system of a tiltrotor in uniform, rectilinear flight. The control action is based on the introduction of higher harmonics in the proprotor blade cyclic pitch motion, and in the cyclic actuation of controllable-stiffness devices located at the roots of the blades. Control laws are obtained through an optimal control methodology that yields the best compromise between control effectiveness and control effort. The numerical investigation concerns the analysis of the performance of the control techniques applied, examining a XV-15 tiltrotor model in airplane mode configuration.
