Control of Large Flexible Structures Using Pole Placement Technique

抄録

The paper considers two methods for active control of large flexible structures using pole assignment for the purpose of stabilizing the neglected dynamics of the unmodeled higher modes of vibration. The first one based on pole placement in a vertical strip has the merit of minimizing control forces and infusing damping in a wide range of modal frequencies. The second approach based on using linear state feedback regulator with Kalman filter observer also uses pole placement in a prescribed region through a quite natural and easy design of the regulator and observer. Both methods have been applied for active stabilization of a flexible feed-support structure for a large parabolic antenna.
