【摘要】 内置式永磁同步电机(IPMSM)模型方程比较复杂,在该领域无位置控制算法比较少。在IPMSM中高速控制算法中,滑模算法因为精度高、鲁棒性强,得到广泛应用。但普通的滑模观测器存在跟踪误差大、抖振明显、抗干扰性能差等缺点。本文为了克服这些缺点,提出了一种基于自抗扰控制的改进超螺旋滑模观测器。首先通过建立超螺旋观测算法来减少系统的抖振。其次,通过改进滑模切换函数,添加自适应复数滤波器来增强算法的跟踪性能。最后,通过自抗扰控制算法结合锁相环来提高系统的抗干扰性能。本文通过仿真模型和实验对比,进一步证明了基于自抗扰控制的改进超螺旋滑模控制系统的稳定和优良性能。更多还原

【Abstract】 The model equation of the interior permanent magnet synchronous motor(IPMSM) is rather complex and there are relatively few positionless control algorithms in this field.Among the high-speed control algorithms for IPMSM,the sliding mode algorithm has been widely applied due to its high precision and strong robustness.The general fullorder synovium observer has some disadvantages such as large tracking error,obvious buffeting and poor anti-interference performance.In order to overcome these shortcomings,an improved adaptive super spiral sliding mode observer is proposed based on active disturbance rejection control.Firstly,the buffeting of the system is reduced by establishing the super spiral sliding mode observation algorithm.Secondly,the tracking performance of the algorithm is improved by improving the synovial switching function and the adaptive complex filter.Finally,the anti-interference performance of the system is improved by combining the active disturbance rejection control algorithm with the phase-locked loop.The stability and excellent performance of the improved adaptive superspiral synovial control system based on the state extended observer are further proved by simulation model and experimental comparison.更多还原
