【摘要】：為揭示非接觸移動(dòng)供電系統(tǒng)參數(shù)擾動(dòng)的產(chǎn)生、傳播及影響機(jī)理,首先采用廣義狀態(tài)空間平均建模方法,建立了4種基本雙邊諧振補(bǔ)償拓?fù)涞南到y(tǒng)不確定模型;其次,研究了電磁耦合機(jī)構(gòu)相對(duì)距離和工況變化導(dǎo)致的互感及負(fù)載擾動(dòng)特性,并依此推導(dǎo)出軟開(kāi)關(guān)調(diào)制模式下的系統(tǒng)頻率擾動(dòng)規(guī)律;第三,基于參數(shù)擾動(dòng)模型分析了互感、負(fù)載及頻率變化對(duì)系統(tǒng)輸出的影響,并通過(guò)計(jì)算系統(tǒng)結(jié)構(gòu)奇異值分析了不同補(bǔ)償拓?fù)湎到y(tǒng)的魯棒穩(wěn)定性;最后,針對(duì)一套雙邊串聯(lián)諧振補(bǔ)償系統(tǒng),對(duì)互感及負(fù)載偏離標(biāo)稱值條件下的系統(tǒng)魯棒性進(jìn)行了驗(yàn)證實(shí)驗(yàn).實(shí)驗(yàn)波形表明:當(dāng)互感和負(fù)載分別在標(biāo)稱值(12.15μH、5.00Ω)與攝動(dòng)值(9.51μH、12.55Ω)之間變化時(shí),系統(tǒng)仍然是魯棒穩(wěn)定的,采用PI控制能較好地抑制其對(duì)負(fù)載輸出電壓的影響.
[Abstract]:In order to reveal the generation, propagation and influence mechanism of parameter disturbance in contactless mobile power supply system, four kinds of system uncertainty models of basic two-sided resonant compensation topology are established by using generalized state space average modeling method. Secondly, the characteristics of mutual inductance and load disturbance caused by the relative distance and operating condition of electromagnetic coupling mechanism are studied, and the frequency disturbance law of the system under soft-switching modulation mode is deduced. Thirdly, based on the parameter perturbation model, the effects of mutual inductance, load and frequency change on the output of the system are analyzed, and the robust stability of different compensated topological systems is analyzed by calculating the singular values of the system structure. Finally, for a two-sided series resonant compensation system, the robustness of the system under the condition of mutual inductance and load deviation from the nominal value is verified. The experimental waveforms show that the system is robust and stable when the mutual inductance and load vary between the nominal value (12.15 渭 H) 5.00 惟 and the perturbation value (9.51 渭 H ~ (-1) 12.55 惟), respectively. The effect of PI control on the load output voltage can be well restrained.
