| 2 | 航空机电作动永磁同步电机自抗扰控制研究综述显示文摘永磁同步电机(Permanent magnet synchronous motor,PMSM)构成的机电作动系统在航空装备中具有广泛的应用,PMSM的转矩响应、稳态定位精度等指标直接影响着航空装备的性能。然而航空机电作动中存在电机本体参数摄动、载荷波动等扰动,为抑制扰动对驱动系统动静态指标的影响,PMSM自抗扰控制成为研究热点。以航空机电作动系统为背景,梳理机电作动中存在的多源扰动,对近年来自抗扰控制在PMSM高性能伺服中的研究成果进行总结,综述强抗扰反馈控制律、电流环抗扰控制策略、速度及位置环扰动观测器的研究现状。最后,归纳航空领域机电作动面临的研究难点及挑战,并对PMSM自抗扰控制的发展趋势进行展望。 | 刘春强 骆光照 涂文聪 | 2021 | 电气工程学报2021，16，4： | 8 |
| 3 | 双质量弹簧基准问题自抗扰控制研究显示文摘本文研究了自抗扰控制(ADRC)方法在双质量弹簧基准问题的应用.传统的自抗扰控制方法倾向于使用高增益控制来抑制扰动和模型不确定性,但是对于双质量弹簧基准问题,高增益在评分中受到较大惩罚,而且对于模型参数变化没有足够的鲁棒性.为解决这一问题,本文对ADRC设计提出了两种改进方案.首先,为了减小控制信号的幅度,将扩张状态观测器(ESO)的一个极点配置在原点.其次,采用阻尼比来调整带宽.结果表明,所提出的ADRC设计可以很好地解决双质量弹簧基准系统的控制问题. | 李健 张彬文 谭文 | 2020 | 控制理论与应用2020，37，4： | 1 |
| 4 | An adaptive sliding mode controller design to cope with unmatched uncertainties and disturbance in a MEMS voltage reference source显示文摘Tunable micro-electro-mechanical systems(MEMS)capacitors as the fundamental parts are embedded in MEMS AC voltage reference sources(VRS).Being concerned with the accuracy of the output voltage in the reference sources,it gets important to address uncertainties in the physical parameters of the MEMS capacitor.The uncertainties have the great inevitable potentiality of bringing about output voltage perturbation.The output deterioration is more remarkable when the uncertainties are accompanied by disturbance and noise.Manufacturers have been making great attempts to make the MEMS adjustable capacitor with desired rigorous physical characteristics.They have also tried to mitigate physical parameter veracity.However,ambiguity in the values of the parameters inescapably occurs in fabrication procedures since the micro-machining process might itself suffer from uncertainties.Employing a proportional integral(PI)adaptive sliding mode controller(ASMC),both terms of matched and unmatched uncertainties as well as the disturbance,are addressed in this work for the MEMS AC VRS so that a strict voltage is stabilized while the system is simultaneously subjected into uncertainties and exogenous disturbance.Cross-talk,some inertial forces,and electrostatic coercions may appear as matched and unmatched disturbances.Alteration in stiffness and damping coefficients might also take place as matched uncertainties due to variations in the fabrication process or even working environment.The simulation results in the paper are persuasive and the controller design has shown a satisfactory tracking performance. | Ehsan Ranjbar Mostafa Yaghoubi Amir Abolfazl Suratgar | 2021 | Control Theory and Technology2021，19，2： | 0 |
