摘要
针对永磁同步直线电机在控制过程中由于复杂扰动的干扰,传统的控制算法难以对电机实现高精度位置跟踪控制的问题,提出了一种干扰观测器复合PID的控制方法,通过干扰观测器观测干扰,然后通过PID反馈控制方式抑制和补偿外部干扰。将所设计的控制算法在dSPACE半实物仿真平台上进行验证,目的是证明所设计的控制算法在实物上也能达到理想效果。实验结果表明,复合控制算法与传统的PID算法相比,有着较明显的精度提升。
In view of the interference of complex disturbances in the control process of permanent magnet synchronous linear motors,traditional control algorithms are difficult to achieve high-precision position tracking control of the motor.The paper proposes a control method of the disturbance observer compound PID.The disturbance is observed by the disturbance observer,and then the external disturbance is suppressed and compensated by the PID feedback control method.The designed control algorithm is verified on the dSPACE hardware in the loop simulation platform.The purpose is to prove that the designed control algorithm can also achieve the desired effect on the physical object.The experimental results show that the compound control algorithm has better results than the traditional PID algorithm,obvious accuracy improvement.
