Oscillation Problem in Pitch Angle Control of Winged Body

The requirements in pitch angle control of winged body are a very fast response with as less oscillation as possible. The oscillation can damage the equipments which are carried within the body. The main problem to cope with is in relatively fast and oscillatory dynamics of the rocket and slow actuators and sensors. We solve the problem by using predictive approach. The main idea of this approach is in process output prediction based on decomposed process model. The decomposition enables the extension of model-based approach to the processes with integrative behavior such as the rocket pitch angle control. The proposed approach gives a framework to design a control for a wide range of processes. In the paper the predictive design methodology was compared to the classical approach. The proposed approach gives a very fast response. Moreover, amplitude oscillation of the winged body are kept low. Copyright c ©2005 IFAC
