| Abstract |
This paper describes an approach to hierarchichal modular control for an electromagnetic aircraft
launching system for the aircraft carrier of the future. The purposes are to analyze the possibility of
improving the control performance using efficient evaluation of switching conditions, and to explore
the different options for the basic control design and the way in which these designs will be tested
using the Virtual Test Bed (VTB) Software. After the descripition of the application of deadbeat
control, in conjunction with predictive algorithms, to the Control, back electro-magnetic force (emf)
generated by FEA (Finite Element Analysis) is discussed. The non-ideal shape of the back emf
produces torque ripple in the control. It is shown that this ripple can be easily compensated for by the
new control scheme proposed. The new control scheme is tested under two different conditions: twophase
control (or DC brushless) and three-phase control (AC brushless). |
