【摘要】：目前的無軸承異步電機(jī)解耦控制策略沒有考慮定子電流動態(tài)影響,限制了其控制性能的提高.為此,本文首先分析了電機(jī)的數(shù)學(xué)模型,在考慮轉(zhuǎn)矩系統(tǒng)定子電流動態(tài)的前提下,建立了無軸承異步電機(jī)的狀態(tài)方程;在系統(tǒng)可逆性分析的基礎(chǔ)上,解析推導(dǎo)出了無軸承異步電機(jī)的逆系統(tǒng)動態(tài)數(shù)學(xué)模型;基于逆系統(tǒng)方法,研究了轉(zhuǎn)速、轉(zhuǎn)子磁鏈和兩個徑向位移分量之間的動態(tài)解耦控制策略.仿真研究結(jié)果表明:控制系統(tǒng)具有優(yōu)良的動態(tài)解耦性能和較強(qiáng)的抗負(fù)載撓動能力.所提出的解耦控制策略是有效的、可行的,并可在一定程度上簡化控制系統(tǒng)結(jié)構(gòu).
[Abstract]:The current decoupling control strategy of bearingless asynchronous motor does not consider the dynamic effect of stator current, which limits the improvement of its control performance. Firstly, the mathematical model of the motor is analyzed, and the state equation of the bearingless asynchronous motor is established on the premise of considering the stator current dynamics of the torque system. Based on the analysis of the reversibility of the system, the dynamic mathematical model of the inverse system of the bearingless asynchronous motor is derived, and the dynamic decoupling control strategy between the rotor flux, rotor flux and two radial displacement components is studied based on the inverse system method. The simulation results show that the control system has excellent dynamic decoupling performance and strong anti-load torsion ability. The proposed decoupling control strategy is effective and feasible, and can simplify the control system structure to a certain extent.
