Instructor: Dr. Ing. Kimon P. Valavanis (kimon.valavanis@du.edu)

John Evans Professor, Director, Unmanned Systems Research Institute

University of Denver


Course Summary: The course provides a comprehensive study of unmanned fixed-wing and rotorcraft navigation and control, including a review of kinematics, dynamics and equations of motion, sensors, identification, controller design and implementation, as well as advances in unmanned aviation technology. A very detailed survey of linear, linearized, nonlinear and soft-computing based controller designs are discussed, the main focus being on helicopter navigation and control designs. A comprehensive comparison of advantages and limitations of implemented techniques follows, subsequently introducing a generalized ‘one-fits-all’ flight control system (FCS) in which the specific controller design approach is a plug-in-plug-out module. Implementation details and how to guarantee task execution given strict timing requirements is detailed. Case studies include simulation and experimental results for several prototype UAVs. Prerequisites: Knowledge of control systems is required. However, all required background information will be presented in class.


Schedule: Nov.7th to Nov.11th,2016, 9:00 AM—12:00 noon, 6th floor, Bld# 3 in SCUT.


Intended audience: The course is suitable for advanced M.Sc. and PhD students who conduct research in (linear/nonlinear) control systems, robotics, UAVs, etc.
