【摘要】：永磁電機(jī)開環(huán)控制系統(tǒng)容易出現(xiàn)不穩(wěn)定的震蕩現(xiàn)象。以三相永磁同步電機(jī)開環(huán)控制系統(tǒng)為例,推導(dǎo)了系統(tǒng)的小擾動數(shù)學(xué)模型。根據(jù)線性系統(tǒng)理論中狀態(tài)轉(zhuǎn)移矩陣特征根判別穩(wěn)定性的方法,詳細(xì)分析了轉(zhuǎn)速、定子電阻、定子電感、勵磁磁鏈、轉(zhuǎn)動慣量以及負(fù)載等參數(shù)變化時對系統(tǒng)穩(wěn)定性的影響規(guī)律并進(jìn)行了實驗驗證。此推導(dǎo)和分析過程可以推廣至其它永磁同步電機(jī)系統(tǒng)中,結(jié)論有助于此類系統(tǒng)參數(shù)合理設(shè)計與穩(wěn)定運(yùn)行。
[Abstract]:The open loop control system of permanent magnet motor is prone to unstable oscillation. Taking the open loop control system of three phase permanent magnet synchronous motor as an example, The small disturbance mathematical model of the system is derived. According to the characteristic roots of the state transfer matrix in the linear system theory, the rotational speed, stator resistance, stator inductance, excitation flux are analyzed in detail. The influence of moment of inertia and load on the stability of the system is verified by experiments. This derivation and analysis process can be extended to other permanent magnet synchronous motor (PMSM) systems. The conclusion is helpful to the reasonable design and stable operation of the system parameters.
