Clayton Second semester 2008 (Day)
Synopsis
This unit covers control theory for aerospace systems with the use of state-space techniques. The state-space of dynamic systems and resulting equations are covered. Concepts of controllability, observability, detectability and the state-transition matrix follow. Classical control concepts including root-locus and frequency-response techniques are set in context of their importance in robust control. Compensators for aerospace systems with full and reduced-order linear observers, parametric optimization and optimal control via kalman filtering. Linear quadratic optimal controllers. The equations of motion for dynamic systems with controllers determined with computational analysis in Matlab.
Objectives
An understanding of the role of linear algebra in engineering dynamics and controls.
An understanding of modern control theory and its use in aerospace systems.
The concepts of controllability, stabilizability, observability, and detectability and their use in controllers.
An appreciation for optimization techniques, particularly those applied to optimum controllers.
The knowledge of where to go to learn more beyond the content of the course on related and more advanced topics.
A well-rounded individual ability to conduct control system analysis and design via independent hand and computer calculations in Matlab.
An individual ability to determine the behavior of simple aerospace dynamic systems and develop strategies to control that behavior, qualitatively and quantitatively.
An individual ability to determine the state-transfer matrix, determine the SISO transfer function, design regulators and full/reduced-order/linear quadratic control observers.
An individual ability to optimize a dynamic system based on the mathematical model of the system and linear optimization theory.
Presenting student work in a cogent and concise manner.
