    摘要:

    提出采用多參數(shù)統(tǒng)一方法，把多個(gè)參數(shù)變化的特性綜合到一個(gè)參數(shù)的變化上，用于在線實(shí)時(shí)更新永磁同步電動(dòng)機(jī)轉(zhuǎn)矩算法的控制參數(shù)。該參數(shù)統(tǒng)一方法基于電動(dòng)機(jī)全狀態(tài)實(shí)驗(yàn)同時(shí)結(jié)合實(shí)時(shí)轉(zhuǎn)矩辨識(shí)控制策略在線補(bǔ)償，充分考慮了電動(dòng)機(jī)在磁場(chǎng)飽和時(shí)多個(gè)參數(shù)的非線性特性，經(jīng)過(guò)實(shí)驗(yàn)驗(yàn)證，不僅實(shí)現(xiàn)了低速下的高精度最大轉(zhuǎn)矩電流比控制，而且實(shí)現(xiàn)了高速弱磁下的高精度轉(zhuǎn)矩控制，滿足了電動(dòng)汽車(chē)的應(yīng)用要求。

    Abstract:

    Multi-parameter integrated control method was proposed. Multi-parameter variation’s characteristics were integrated into one parameter to update the control parameters of torque algorithm real-timely. This multi-parameter integrated method was on the base of all states experiment of the motor and online search. It made full account of multi-parameter’s nonlinear behavior. Experimental results verified that not only the precise torque control of maximum torque-per-ampere in the low speed, but also the precise torque control in the flux-weakening of high speed were carried out, which met the requirements of the electric vehicle applications.
