      Finite-time disturbance attenuation control problem for singularly perturbed discrete-time systems 

      Abdelrahman, M. A.; Naidu, D. S.; Charalambous, Charalambos D.; Moore, K. L. (1998)
      In this paper we consider the problem of finite-time H∞-optimal control of linear, singularly perturbed, discrete-time systems. The problem is addressed from the game theoretic approach. This leads to a singularly perturbed, ...

      Fuel-optimal trajectories for aeroassisted coplanar orbital transfer problem 

      Naidu, D. S.; Hibey, J. L.; Charalambous, Charalambos D. (Publ by IEEE, 1988)
      The optimal-control problem arising in coplanar orbital transfer using aeroassist technology is addressed. The maneuver involves the transfer from high earth orbit to low earth orbit with minimum fuel consumption. Simulations ...

      FuelOptimal Trajectories for Aeroassisted Coplanar Orbital Transfer Problem 

      Naidu, D. S.; Hibey, J. L.; Charalambous, Charalambos D. (1990)
      The optimal control problem arising in coplanar, orbital transfer employing aeroassist technology is addressed. The maneuver involves the transfer from high Earth orbit to low Earth orbit via the atmosphere with the object ...

      Neighboring Optimal Guidance for Aeroassisted Orbital Transfer 

      Naidu, D. S.; Hibey, J. L.; Charalambous, Charalambos D. (1993)
      A neighboring optimal guidance scheme for a nonlinear dynamic system is devised with stochastic inputs and perfect measurements as applicable to fuel optimal control of an aeroassisted orbital transfer vehicle. For the ...
