Abstract
The requirements in pitch angle control of winged body are a veryfast response with as less oscillation as possible. Theoscillation can damage the equipments which are carried within thebody. The main problem to cope with is in relatively fast andoscillatory dynamics of the rocket and slow actuators and sensors.We solve the problem by using predictive approach. The main ideaof this approach is in process output prediction based ondecomposed process model. The decomposition enables the extensionof model-based approach to the processes with integrativebehavior such as the rocket pitch angle control. The proposedapproach gives a framework to design a control for a wide range ofprocesses.
