Abstract

The damping of vibrations on aircrafts and rotorcrafts can provide life extension and weight reduction on those structures on which the vibration load is a significant amount of load endurance spectrum. In this work, a hybrid active-passive inertial actuator system is presented. It is based on a ballscrew based actuator, and the power generation is provided by an open windings three phase motor controlled by a dual inverter. Open windings drives allow to achieve greater torque generation with the same DC bus voltage. The PWM is generated accordingly to a novel algorithm based on a combination of two standard SVM algorithms, one for each inverter. The current controller has been tested on a real test bench at the designed working frequency. Also, a force controller has been designed and tested to verify the force values that can be delivered by the actuator at the designed working frequency
