This paper describes an improved version of the H oo control schemes to enhance
the performance and stability of the superconducting generator (SCG). A Flexible
control structure is proposed, designed and implemented to overcome the problems
that resulting from the low inherent damping nature of the superconducting generator.
The controller is implemented using a detailed nonlinear simulation. The time‌invariant state space model is also obtained and the system oscillatory modes are
given. The simulation results are represented in comparison with other results
which obtained using conventional control systems. The linear time response
simulation and the non-linear time response with the transient stability analysis
confirms the superiority of the proposed controller and illustrate its effectiveness in
system stabilization.
