GWO: PID	K_P = 1.5531, K_I = 0. 1954, K_D = 0.9517	11.95
SGWO: PID	K_P = 0.5422, K_I = 0. 0801, K_D = 0.0295	10.99
GWO: AFPID	K₁ = 0.7148, K₂ = 1.0995 K_P1 = 0.1442, K_I1 = 0.1701, K_D1 = 0.6822 K_P2 = 0.1867, K_I2 = 1.0645, K_D2 = 1.501	7.9544
SGWO: AFPID	K₁ = 0.7163, K₂ = 0.0011 K_P1 = 0.2817, K_I1 = 0.5591, K_D1 = 0.5595 K_P2 = 0.2474, K_I2 = 0.6671, K_D2 = 0.6676	7.774
