Fuzzy-PI dual-band voltage negative feedback con trol and nonlinear optimal excitation controller de sign

Generator excitation control is effective to improve power system dynamic performance of the main means. In t his paper, a fuzzy-PI double with voltage mode control and n onlinear optimal excitation control of negative feedback cont rol scheme of parallel operation. And simulation with MATL AB fuzzy logic toolbox real analysis, and adjust parameters t o fit with the band voltage negative feedback nonlinear opti mal excitation controllers in parallel. Simulation results sho w that single machine infinite bus system for the control met hod to suppress the dynamic disturbance environment wit h better adaptability and robustness.
