报告内容简介:
In this talk, we will introduce the design and simulation test results of a six degree-of-freedom, autonomous, trajectory-tracking controller for a fixed-wing vehicle nonlinear dynamics model by Trajectory Linearization Control (TLC). TLC combines an open-loop dynamic inverse of the plant dynamics with a closed-loop tracking-error regulator that accounts for model mismatch, disturbances, and excitation of internal dynamics. Feedback gains are obtained symbolically as a function of the nominal trajectory, thus avoiding the use of gain scheduling, and enabling operation across the full flight-envelope without the need for mode-switching. The design method is presented, and trajectory-tracking simulation results are given for a bank-to-turn, climbing helix trajectory. Further development of the controller for autonomous Payload Directed Flight (PDF) control, upset prevention and recovery flight control and fault tolerant flight control will also be discussed.
