摘要: A Maglev system was modeled by the exact feedback linearization to achieve two same linear subsystems. The proportional-integral-differential controllers (PID) based on particle swarm optimization (PSO) algorithm with four different inertia weights were then used regulate both These Fixed Inertia Weight (FIW), Linear Descend (LIW), Differential (LDW), and mixed weight (FIW–LIW-LDW). On other hand, parameters  of PSO-PID via (FIW–LIW-LDW) optimized, parameter values  in electromagnet 1 2 0.4. Simulation results demonstrate that control performance robustness of superior three single weights. For 1, overshoot controller reduced 3.36% than FIW, 5.81% LIW, 6.34% LDW; for 2, 1.07% 12.56% 7.97% adjusting time 0.395s 34.1s 33.494s LDW
