For improving fiber optic current transformer system’s dynamic response
the closed-loop detection principle of the fiber optic current transformer was analyzed
a system model was established
and its parameter uncertainty was considered.Therefore
a robust controller was designed with robust control theory according to the suitable performance index for the system.The simulation results indicate that the robust controller achieves high dynamic and robust performances when the parameters of the fiber optic current transformer system vary in a wide range.
