摘要
针对电流源逆变器高速电机驱动系统存在的动态响应慢、参数整定复杂问题,该文提出一种离散虚拟矢量预测电流控制策略,交流侧采用离散空间矢量调制技术合成大量虚拟矢量,其多样性提高控制自由度与精确度,不连续性保证一定的抗参数扰动能力;利用无差拍技术优化输出电流矢量选择过程,减少计算量;所提策略在保证稳态性能的同时提高了动态响应性能。直流侧通过无差拍预测所需输入电压来控制母线电流,不依赖于电机运行状态判断。
In response to the issues of slow dynamic response and complex parameter tuning in current source inverter high-speed motor drive systems,this paper proposes a discrete virtual vector predictive current control strategy.In this strategy,a multitude of virtual vectors are synthesized using discrete space vector modulation technology on the AC side.The diversity of these vectors enhances control flexibility and precision,while their discontinuity ensures resistance to parameter disturbances.The selection process for the output current vector is optimized using a deadbeat technique,which reduces computational effort.This strategy not only maintains steady-state performance but also improves dynamic response.On the DC side,the bus current is controlled by predicting the required input voltage through a deadbeat technique,without relying on the assessment of the motor's operational status.
