Conclusions The ORW control applied to two aeroelastic systems results in a better performance in terms of smoothness of response and decay time, but a greater sensitivity to process noise when compared to the traditional output-weighted optimal cont

State estimation is difficult when the system has multiple modes of operation. Modal transitions create discontinuities in the reference point for the local state variables. The uncertain reference point increases the ambiguity in the state measureme

Tracking an agile target is made dif cult by a multiplicity of possible motionmodes. An earlier paper (Sworder, D. D., Vojak, R., and Hutchins, R. G., “Gain Adaptive Tracking,” Journal of Guidance, Control, and Dynamics, Vol. 16, No. 5, 1993, p

The equations of state evolution of a hybrid system are nonlinear and generate non-Gaussian sample paths. For this reason, the optimal, mean-square estimate of the state is difficult to determine. In an earlier paper (Ref. 1), a useful approximation

The optimal, mean-square estimate of the state of a hybrid system is difficult to determine because the equations of state evolution are nonlinear and non-Gaussian. When there is a direct, albeit noisy, measurement of the modal state, it is possible

Properly joining the different modes of a multiregime tracker is difficult. This paper describes a novel, image-based algorithm for tracking a maneuvering target. The form of the algorithm is like the extended Kalman filter, but the gain adjustment u

Models of a human decisionmaker involve abstractions of certain cognitive variables. These quantities are intermediaries in a personal input-output relation. In earlier work on this topic, a stimulus/hypothesis evaluation model was developed. In this

A control problem is considered where the coefficients of the linear dynamics are functions of a noisily observed Markov chain. The approximation introduced is to consider these coefficients as functions of the filtered estimate of the state of the c
