Guidance & Steering

The development of aerospace flights has led to the development of powerful control methods adapted to the strong constraints of this field: multi-actuators multi-sensors with important performance requirements. These methods were very quickly deployed in the military aeronautics (reactivity) before massively broadcast in the civil aeronautics. With the reinforcement of competition, it is crucial to manage energy as efficiently as possible in order to limit costs while ensuring the comfort and safety of passengers, which makes control systems indispensable. The objective of this project is to train in the methods of design and validation (robustness) powerful control systems, essential in the aerospace industry.

The work to be carried out can be split into three phases which will be addressed as the project progresses. A first phase of bibliographical study, in which the aim is to familiarize with a few notions of flight dynamics, to understand the motion model, and to formalize the specifications for the design of the control laws. A series of lectures will be dedicated to flight mechanics. A second phase of actual design correctors. Depending on the specifications, students will choose from a range of multivariable methods (pole placement, H-infinity, LQG, etc.) an appropriate method for controller computation. A third validation phase consist in robustness analysis methods application to the obtained system.
