Popis: | The design, implementation, and evaluation of a full-envelope control system for the AIAA controls design challenge aircraft is presented. The control problem is divided into separate longitudinal and lateral/directional designs. The longitudinal controller is a Mach number and flight path angle command system, and bank angle is commanded through the lateral/directional autopilot. A cross-axis filter minimizes transient errors during coupled maneuvers. Proportional plus integral plus derivative structure is built into a linear quadratic synthesis problem to generate state feedback gains. An implementable output feedback solution is found through a linear transformation of the state feedback gain matrix. The control system is gain scheduled with dynamic pressure through polynomial curve fits of linear point design gains. Required maneuvers are demonstrated within design specifications except in cases where the physical limitations of the aircraft restrict achievable performance. |
