摘　　要：针对电磁轴承支承的高速飞轮储能转子系统振动抑制问题,提出一种降阶线性自抗扰控制(rLADRC)方法。首先,建立考虑陀螺效应及不平衡力的刚性飞轮转子系统径向四自由度二阶数学模型;其次,将各自由度数学模型中本自由度项作为内部扰动,其他自由度项带来的耦合和不平衡力项作为外界扰动,进而设计降阶线性扩张状态观测器(LESO)对总扰动进行实时估计;最后,设计线性状态误差反馈控制律(LSEF)并对总扰动进行补偿。结果表明:rLADRC能够实现转子径向四自由度之间的有效解耦,与传统分散比例积分微分(PID)控制和线性自抗扰控制相比,具有良好的动态性能和较强的扰动抑制能力,可在全转速范围内实现飞轮转子系统的稳定悬浮和对振动的有效抑制。Aiming at the problem of vibration suppression of high-speed flywheel energy storage rotor system supported by electromagnetic bearings,a reduced order linear active disturbance rejection control(rLADRC)method was proposed.Firstly,a four-degree-of-freedom radial second-order mathematical model of rigid flywheel rotor system was established,which considered gyroscopic effect and unbalanced force.Then,the intrinsic degree of freedom term in the mathematical model of each degree of freedom was treated as the internal disturbance,and the coupling and unbalance force terms introduced by other degrees of freedom terms were considered the external disturbances,a reduced order linear extended state observer(LESO)was designed to estimate the total disturbance in real time.Finally,the linear state error feedback(LSEF)control law was designed,and the total disturbance was compensated.Results show that the rLADRC can effectively decouples the radial four freedom degrees of the rotor.Compared with the traditional decentralized proportional-integral-derivative(PID)control and LADRC,rLADRC has superior dynamic performance and stronger disturbance suppression capabilities,witch can realize stable levitation and effective vibration suppression of the flywheel rotor system in the full speed range.
