Application to Liapunov model-tracking parameter identification for the CH-47 helicopter

This paper reports results obtained in an evaluation study of model-tracking parameter identification for the optimally controlled CH-47 helicopter while in flight. The model is made to track some of the helicopter parameters by means of Liapunov-designed adaptive algorithm. The topics investigated include the accuracy of identification of the time-varying vehicle and the effect of controller feedback upon the performance of the identifier.
