This paper presents some simple fuzzy logic schemes for online tuning proportional-integral controller parameters to improve system robustness. It is shown that, with fuzzy tuning, the reference response is well-damped and the maximum deviation of the disturbance response is reduced even in the case of changing plant parameters. The fuzzy-tuned controllers can then be applied to multiloop control systems using the conventional cascade control principles. Simulation results for a two-mass servo… CONTINUE READING
