摘要：
In order to reveal the generation, propagation and effect mechanism of parameter disturbance in contactless moving power supply system, the generalized state space average modeling method was first used to establish the uncertain model for four basic kinds of bilateral-resonance compensation topologies. Secondly, the mutual inductance and load disturbance characteristics were studied when the relative distance of electromagnetic coupling mechanism and working conditions change. According to this, the system frequency disturbance law under soft-switching modulation mode was deduced. Thirdly, the effect of changes in mutual inductance, load and frequency on the system output was analyzed according to the parameter disturbance model, and also the system robust stability was analyzed by computing structured singular value under different compensation topologies. Finally, a bilateral resonant system in series was used to verify the system robustness when the mutual inductance and load deviate from the nominal values. The experimental waveforms of system electrical variables show that when the mutual inductance and load are varied between nominal values (12.15 μH, 5.00 Ω) and perturbation values (9.51 μH, 12.55 Ω), the system is still robustly stable, and the influence of parameter perturbations on the load output voltage can be well suppressed by PI control. © 2016, Editorial Department of Journal of Southwest Jiaotong University.
