of the aircraft. The results of the data returned from CIFER can be used to correct a flightsimulation [Ref. 14] for further development of the aircraft and flight control system[Ref. 13]. CIFER is a set of utilities tied together with a common interface that processtime domain [Ref. 12](frequency sweep) data into frequency domain data (bode plots).Conducting a manual frequency sweep (CHIRP) provides data for the program to processinto transfer functions and stability derivatives. CIFER includes a utility to fit low ordertransfer functions [Ref. 17] to the high order identified systems. Data created for the CalPoly simulation lab tutorial was processed using CIFER and a simple Simulink model.The model and data were incorporated into a internet based tutorial to demonstratesystem identification to users of the Cal Poly simulation lab. A flight data collectionsystem created in the Cal Poly flight controls lab provides the capability to collectfrequency data for existing aircraft. The system uses low cost consumer grade sensorssending signals through a pcm/cia A/D card to a laptop personal computer.The system created is flexible, powerful, inexpensive, expandable, verified, andeasy to use, fulfilling all of the original design objectives. The software code generatorwas also verified and includes the tools and techniques that can be used to verify futuresimulation models11
