In order to prevent wings vibration due to external interference

for the control object of flexible cantilever beam a scheme of fractional order proportion integration differentiation controller based on parameters self-correction was proposed. After the parameters were optimized by genetic algorithm firstly

they were set online by fuzzy rule for the second time in order to achieve real-time optimum control. Numerical simulation was carried out by Simulink software

and result shows that the proposed fractional order proportion integration differentiation controller has a memory ability and a strong dynamic characterization ability. Compared with the conventional proportion integration differentiation controller

the steady state time of system response decreases by 0.9s under impulse stimulation; the reduced amplitude of system response increases from 88% to 96% under harmonic stimulation; the system tends to be more stable and the response jitter reduces under random stimulation.
