Unformatted text preview: Model-Following State-Feedback Model-Following Model Building MAE 142 Convair NC-131H Total In-Flight Simulator (TIFS) (U.S. Air Force Image) 2 MAE 142 Control-Configured Vehicle (CCV) Design What if your new vehicle design is predicted to have poor dynamics? Option 1: Track down the offending stability derivatives and make changes to the shape/size/weight of the vehicle until the modified derivatives meet requirements. This option is useful early in the design process, when shape, size, and weight distributions can still be modified. Option 2: Use feedback control to augment the vehicle stability derivatives such that the desired stability requirements are met. This option will increase cost and complexity. It may also impact the certification process – if the only way to safely fly the airplane is with the stability augmentation system activated. On the other hand, this option also gives the flight control engineer considerable flexibility in tuning the vehicle's dynamic response. 3 MAE 142 Full-State Feedback Full-state feedback allows the flight control engineer to tailor the vehicle's dynamics...
