    摘 要:針對(duì)傳統(tǒng)建模方式下電機(jī)控制性能易受參數(shù)攝動(dòng)影響的問(wèn)題,提出一種改進(jìn)型無(wú)模型滑模控制方法。建立超局部模型降低控制系統(tǒng)對(duì)電機(jī)參數(shù)的依賴,并結(jié)合新型趨近律設(shè)計(jì)改進(jìn)型無(wú)模型滑模控制器,利用擴(kuò)展滑模擾動(dòng)觀測(cè)器補(bǔ)償系統(tǒng)未知部分。實(shí)驗(yàn)結(jié)果表明,該方法響應(yīng)速度更快,魯棒性更強(qiáng)。

    Abstract: The motor control performance under the traditional modeling approach is susceptible to parameter variety, so an improved model-free sliding mode control method is proposed. It builds an ultra-local model to reduce dependence of the control system on motor parameters, designs an improved model-free sliding mode controller based on the new reaching law, and adopts an extended sliding mode disturbance observer to compensate the unknown part of the system. The experimental results show that this method is of faster response and stronger robustness.
    Key words: permanent magnet synchronous motor; new reaching law; model-free sliding mode control
