Abstract

The effect of bidirectional power flow on the power distribution system of an aircraft is addressed in this paper. The active vibration control problem of the tail surface of an aircraft using piezoelectric actuators is chosen to motivate the study presented. A simple dynamic model of the tail surface is developed. A current controlled switched-mode power amplifier is used to drive the actuators. The integration of the `amplifier-actuator' into the power distribution system of the aircraft is studied in detail. The effect of circulating energy between the actuators and the DC bus on the voltage on the bus is explained. Solutions to avoid instability and undesirable distortion in the DC bus voltage are proposed.
