Embodiment Construction
[0107] The test object of the present invention is a certain type of high-performance flight simulation turntable. Based on the application object, the specific implementation steps of the NLPID controller parameter tuning based on the adaptive ant colony algorithm proposed by the present invention are as follows:
[0108] Step 1: Set the interrupt sampling interval to 0.0008s, set the initialization parameters α=1.5, β=4.5, ρ min =0.2,τ ij = 1, Δτ ij (0)=0, m=20, ρ 0 =0.15,R 1 =150, R 2 = 100, δ 1 =0.002, δ 2 =0.0013, δ=0.01, α'=0.6, N Cmax =100, Q=300; After many times of debugging, determine the control coefficient β 0 , β 1 and beta 2 The approximate range of β 0 [0.01, 0.09], β 1 [770,790], β 2 [0.1,0.7];
[0109] The second step: the number of cycles N C ←N C +1;
[0110] The third step: the taboo table index number k=1 of the ant;
[0111] The fourth step: the number of ants k←k+2;
[0112] Step 5: Every two ants, as a party, jointly select an optim...
