【摘要】：本文對(duì)考慮鐵耗情況下的感應(yīng)電機(jī)間接矢量控制方法進(jìn)行了研究,分析了其影響機(jī)理,并對(duì)其進(jìn)行線性化補(bǔ)償。由于鐵耗的存在,常規(guī)間接矢量控制系統(tǒng)所采用的定向方法會(huì)導(dǎo)致系統(tǒng)出現(xiàn)偏差,使系統(tǒng)輸出轉(zhuǎn)矩減小,帶載能力減弱,在弱磁區(qū)的恒功率運(yùn)行范圍縮短。本文根據(jù)考慮鐵耗的感應(yīng)電機(jī)等效電路,推導(dǎo)考慮鐵耗情況下的定向控制方程,并且提出了線性化的補(bǔ)償方法,以利于工程實(shí)現(xiàn)。最后,通過基于DSP的全數(shù)字主軸驅(qū)動(dòng)器進(jìn)行了物理試驗(yàn),試驗(yàn)證明本文所提出方法的可行性和有效性,對(duì)主軸驅(qū)動(dòng)系統(tǒng)性能地提高是非常顯著的。
[Abstract]:In this paper, the indirect vector control method of induction motor considering iron loss is studied, the influence mechanism is analyzed, and the linearization compensation is carried out. Due to the existence of iron loss, the orientation method used in the conventional indirect vector control system will lead to the deviation of the system, the output torque of the system will be reduced, the load capacity of the system will be weakened, and the operating range of constant power in the weak magnetic field will be shortened. Based on the equivalent circuit of induction motor with iron loss, the directional control equation with iron loss is derived, and a linearized compensation method is proposed to facilitate the engineering realization. Finally, through the physical experiment of the digital spindle driver based on DSP, the experiment proves the feasibility and effectiveness of the proposed method, and it is very significant to improve the performance of the spindle drive system.
