Fault detection, isolation, and estimation (FDIEI functions and reconfiguration strategres for Right control systems present major technical chaIImges, primarily because of uncertainties resulting from limited observability and an almost unlimited variety of malfunction and damage scenarios. This paper deals primarily with a portion of the probIem, i.e., global FDIE for single impairments of control effectors. Reference is also made to reconfiguration strategies. Polynomial neural networks are synthesized using a constrained error criterion to obtain pairwise discrimination between impaired and no-fail conditions and isolation h e e n impairment classes. The pairwise discrimi~tora~re thm combined in a form of voting logic Polynomial netwarks are also synthesized to obtain estimates of the amount af effector impairment. The Algorithm for Synthesis of Polynomial Networks (ASEN) arrd related methods are used to create the networks, which are highorder, linear or nonlinear, analytic, multivariate functions of the in-flight observables. This paper outlines the design procedure, including database preparation, extraction of waveform features, network synthesis techniques, and the architecture of the FDIE system that has been studied for the Control Reconfigurable Combat Aircraft. Representative performance results are prwvided.

In-flight simulat.ions are normally accomplished by using control laws which depend on accurate knowledge of the stability derivatives of the host aircraft. Degraded performance may result if the stability derivatives deviate considerably from their presumed values. Gain scheduling can compensate for parameter variations, but this form of open-loop compensation m y require extensive flight testing for fine tuning. This paper implements an adaptIve mntrol law to compensate for changing aircraft parameters. The step-response matrix required by 'the control law 1s identified recursively using a recently developed technique which does not requ'ire special "test" signals and which discounts old data depending on the input excitation detected. Tracking fidelity i s maintained despite parameter changes. The control design package MATRIXx is used to test the adapttve system. The performance of the resulting system i s excel lent and demonstrates the relative advantages of adaptive controlliers for in-flight simulation.
