Efficient Stabilization of Hybrid Coulomb Spacecraft Formations using Control Lyapunov Functions
Adam M Tahir
A control allocation algorithm using control Lyapunov functions to determine stabilizing charges and thrusts of hybrid Coulomb spacecraft formations (HCSFs) is presented. The goal…
Model Predictive Control of Collinear Coulomb Spacecraft Formations
Adam M Tahir
A model predictive control scheme to stabilize desired configurations of collinear Coulomb spacecraft formations is derived in this paper. The nonlinearities of the dynamics with r…
On the mixed monotonicity of polynomial functions
Adam M Tahir
In this paper, it is shown that every polynomial function is mixed monotone globally with a polynomial decomposition function. For univariate polynomials, the decomposition functio…
Synthesis of Interval Observers for Nonlinear Discrete-Time Systems
Adam M Tahir, Behcet Acikmese
A systematic procedure to synthesize interval observers for nonlinear discrete-time systems is proposed. The feedback gains and other matrices are found from the solutions to semid…
