Abstract: Optimal control functions in the sense of minimum settling time and minimum fuel or energy consumption are derived for several different single-axis attitude control systems. The systems treated ...

Abstract: A finite-difference solution is presented for the laminar, two-dimensional, viscous, incompressible wake behind a finite flate plate. The plate is infinitely thin and is aligned parallel to a ...

Abstract: The choice of time T for zeroing an initial disturbance with minimum-fuel consumption influences the dependence of the switching instances on the phase variables. For a set of discrete values ...

Abstract: Application of Pontryagin’s optimal principle to control system problems eventually requires that a two-point boundary-value problem be solved. For plants whose equations of motion are greater ...

Abstract: This paper presents an extension to the problem discussed in previous papers by Irmgard Flügge-Lotz and Mih Yin.2, 3 In the full third-order problem it was found desirable to modify the ...
