Optimal control of time evolution systems: Controllability investigations and numerical algorithms
Optimal control problems for partial differential equations of evolution, mostly of parabolic type, are considered. The means of control are a nonhomogeneous boundary condition or forcing term. A hierarchical control problem ...
Design against resonance
A method for maximizing the distance from the spectrum of an analytic, symmetric matrix with distinct eigenvalues from a given frequency is proposed. The method models the classical approach from optimization of finding ...
Optimal trajectories for the aeroassisted flight experiment
The aeroassisted flight experiment (AFE) is to simulate a transfer from a geosynchronous Earth orbit (GEO) to a low Earth orbit (LEO). Specifically, the AFE spacecraft is released from the Space Shuttle and is accelerated ...
Determination of linear system random response spectral moments by Hilbert transforms
The stationary response of a linear system excited by a stationary random process is considered. A previously developed approach is extended to determine both the even and odd integer order spectral moments of the system ...
