摘要
针对基于磁场定向控制的永磁直线同步电机(PMLSM)伺服系统的位置精准控制问题,提出了一种TSK型递归模糊神经网络(TSKRFNN)控制方法。在考虑了系统易受参数变化、外部扰动和摩擦力等不确定性因素影响的基础上,建立了含有不确定性因素在内的PMLSM动态数学模型;利用TSKFRNN对系统同时进行了实时在线的结构学习和参数学习,提高了系统抑制不确定性因素的鲁棒性,保证了系统的动态跟踪性能。实验及研究结果表明:与模糊神经网络PID控制方法相比,TSKFRNN可以有效辨识电机参数,抑制系统的不确定性对系统伺服性能的影响,提高了系统的鲁棒性和跟踪性能。
In order to solve the problem of position precision control of permanent magnet linear synchronous motor (PMLSM) servo system based on field-oriented control, a TSK-type recurrent fuzzy neural network (TSKRFNN) control method was proposed. Considering that system was susceptible to uncertainties such as parameter changes, external disturbances and frictions, a PMLSM dynamic mathematical model with uncertainties was established.The TSKRFNN was used to do structure learning and parameter learning of the system at the same time.The system could be automatically increased the neuron resistance to external disturbance and improved the robustness of the system,ensured the dynamic performance of the system.Experimental results show that,compared with the fuzzy neural network type PID, the proposed method can identify the parameters of PMLSM, suppress uncertainties of the system and improve the robust performance and tracking performance of the system effectively.
