中文摘要
      针对传统滑模观测器由于抖振而导致永磁同步电机转子信息观测精度低的问题,设计了一种基于二阶广 义积分器(SOGI)的自适应高阶滑模转子信息观测器.首先,通过构造一种具有增益自适应跟踪算法的高阶滑模观 测器,解决传统滑模观测器引入低通滤波器所造成相位滞后与幅值衰减问题,减少抖振对观测精度的影响;其次,使 用SOGI与归一化正交锁相环技术获取位置和速度信息,将转子角频率反馈至SOGI模块作为其中心频率,减少负载 扰动和死区效应引起的谐波和噪声的污染,并通过Lyapunov稳定性定理证明了系统的稳定性;最后,搭建永磁同步 电机无位置传感器控制系统,通过仿真以及实验验证了该方法的有效性.实验结果表明,相比于传统的滑模观测器, 改进后的转子信息观测器有效提高了转子位置估计精度,抑制了滑模抖振与谐波.
英文摘要
      Aiming at the problem of low observation accuracy of rotor information caused by chattering of traditional sliding mode observer (SMO) in sensorless control system of permanent magnet synchronous motor, an adaptive high order SMO of rotor information based on second order generalized integrator (SOGI) is designed. Firstly, a high-order sliding mode observer with a gain adaptive tracking algorithm is constructed, to solve the phase lag and amplitude attenuation caused by the introduction of low-pass filter in the traditional SMO and reduce the effect of buffeting on the observation accuracy. Secondly, the rotor information is obtained through the SOGI and orthogonal phase locked loop (PLL), the angular frequency of the rotor is then feedback to SOGI module. By doing this, the frequency adaptive tracking of SOGI is thus be realized, and the influence of harmonic and noise caused by load disturbance and dead zone effect can be reduced. The stability of the system is verified by the Lyapunov stability theory. Finally, the sensorless control system of permanent magnet synchronous motor was constructed, and the effectiveness of the proposed method was verified by simulation and experiment. The experimental results show that compared with the traditional SMO, the improved rotor information observer can effectively improve the accuracy of rotor position estimation, and suppress sliding mode chattering and harmonics.
