Course Description

The intent of the course is to provide a “top-level” introduction to Modern Flight Control Systems (FCS’s).  Basic elements of modern FCS’s are reviewed along with typical basic structures and system elements for modern fly-by-wire FCS’s. Modern analysis and simulation tools are introduced and demonstrated using MATLAB® and SIMULINK®, the advanced engineering computer programs. Students use the basics of MATLAB and the associated Control system Toolbox during the course. Handling qualities criteria and special issues related to modern complex FCS’s such as Pilot Induced Oscillations (PIO’s) are reviewed.  The need for systematic closed-loop handling qualities evaluations is emphasized. The effects of common control system feedback implementations are presented using MATLAB and the NTPS variable stability ground simulator (VSGS).   Command path shaping and nonlinearities in the command path, such as response limiters, time delay and rate limiting are also introduced and discussed.  Course learning objectives are reinforced when students complete two related mini-design/evaluation projects on the VSGS. The objective of the course is to provide a high level of understanding of the Principles, Issues, and Test Methods related to modern FCS’s  not to produce FCS designers. Daily review tutorials, oral exams (2) and a final written exam are included in the course.
