永磁同步电机无位置传感器鲁棒无源控制

提出一种永磁同步电机无位置传感器鲁棒无源控制方法。首先,建立了永磁同步电机耗散哈密顿数学模型。其次,在耗散哈密顿数学模型的基础上,设计了永磁同步电机鲁棒无源控制器,有效提高了永磁同步电机控制系统电流环和转速环的抗扰动性能和动态响应性能。与此同时,设计一种基于反电势的新型锁相环对转子位置和转速进行进一步估算,避免引入反正切函数和微分运算带来的转子位置估计抖振问题。实验结果验证了提出的无源控制方法的有效性。

Sensorless Robust Passive Control of Permanent Magnet Synchronous Motor

A sensorless robust passive control method for PMSM was proposed.Firstly,the dissipation Hamiltonian model of PMSM was established.Secondly,based on the dissipative Hamiltonian mathematical model,the robust passive controller of PMSM was designed to effectively improve the anti disturbance and dynamic response performance of current loop and speed loop of PMSM control system.At the same time,a new phase-locked loop based on back EMF was designed to further estimate the rotor position and speed,avoiding the chattering problem of rotor position estimation caused by the introduction of back tangent function and differential operation.The experimental results verify the effectiveness of the proposed passive control method.
