摘要
对磁场定向控制的理论进行了分析,选择基于转差率的间接矢量控制方案,仿真和探讨了影响解耦控制的因素。使用Matlab/Simulink对解耦效果进行了仿真解析,仿真结果验证了该方案具有较好的控制性能。在理论分析和仿真验证的基础上,搭建了基于TM320F28335型DSP的硬件系统实验平台,并在11 kW电机拖动实验平台上进行了相应实验。实验结果表明该方案实现了转矩和磁通解耦控制,控制系统简单易行、动态响应快且超调量小、稳态精度高。
The theory of field oriented control was analyzed,the indirect vector control scheme based on slipfrequency was selected and the factors affecting the decoupling control were simulated and discussed. Decouplingeffect was simulated using Matlab/Simulink,and the results show that the control performance is better. Based on theoretical analysis and simulation verification,a TM320F28335 hardware platform was built,the correspondingexperiment was carried out on the 11 kW motor drive experiment platform. Experiments show that this method canrealize the decoupling control of torque and flux,the system is simple and the response is fast and accurate.
