Wavelet-based excitation representation and response determination of linear and nonlinear systems
The dissertation determines the evolutionary spectrum of non-stationary stochastic processes and describes the time-varying characteristics of the response of linear and nonlinear dynamic systems subject to non-stationary ...
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 ...
Robust momentum manager controller for space station applications
An innovative methodology to design a robust Control Momentum Gyro (CMG) momentum manager for the International Space Station (ISS) is developed. Unlike most other momentum manager designs, which use either a Linear Quadratic ...
A generalized trust region SQP algorithm for equality constrained optimization
We introduce and analyze a class of generalized trust region sequential quadratic programming (GTRSQP) algorithms for equality constrained optimization. Unlike in standard trust region SQP (TRSQP) algorithms, the optimization ...
