Applied Control System Design and Analysis with Aerospace Examples

ME 598

Course Description
Autonomous systems have secured a unique and expanding role in commercial and military applications. Self driving cars, agricultural applications, communication relay nodes, space exploration, and long-duration surveillance missions are examples. Control theory plays a central role in making these systems autonomous. This course will teach advanced control system design methods used in developing autonomous systems using real-world aerospace models.

plane in airThe level of control theory used industry has advanced significantly in the last 20 years. Using my experiences gained in developing aerospace control systems I have configures this course to teach what an engineering student needs to know to work in industry today, and in the future. The control design and analysis examples used throughout the course are real examples of autonomous systems.

This course will cover graduate-level control system design methods for multi-input multi-output linear dynamic systems. Specific topics include: Advanced design and analysis of control systems by state-space methods: classical control review, Laplace transforms, review of linear algebra (vector space, change of basis, diagonal and Jordan forms), linear dynamic systems (modes, stability, controllability, state feedback, observability, observers, canonical forms, output feedback, separation principle and decoupling), nonlinear dynamic systems (stability, Lyapunov methods). Frequency domain analysis of multivariable control systems using singular values. State space control system design methods: state feedback, observer feedback, pole placement, linear optimal control and the robust servomechanism. Robustness theory and analyzing the sensitivity to knowing model parameters. Control design and analysis exercises will be used to reinforce learning of the theory with Matlab-based CAD (computer-aided design) projects that use real aerospace system models.

Goals: Develop the mathematical background and sophistication required to understand the fundamentals of modern control and systems theory used in industry. Learn the concepts involved in modern control and systems theory, in order to prepare for more advanced topics and courses, permit self-learning and enable you to approach and solve real-world problems with confidence.
