Abstract : The report presents the results of the second part of a oneyear study on Dual Control and Identification Methods for Avionic Systems. First, a general theory is developed for designing optimal inputs to identify parameters in linear dynamic systems. It is shown that the optimal energy constrained unput maximizing a weighted trace of the Fisher information matrix is an eigenfunction of a positive selfadjoint operator corresponding to its largest eigenvalue. Several numerical algorithms are described for computing the optimal inputs. A computer program based on the Riccati Equation algorithm is developed and used for computing optimal elevator deflection time histories to identify the short period stability and control derivatives of C8 aircraft.
