采用传统控制策略对低脉冲逆变装置的交流电流控制器进行设计时，控制器系统带宽通常会接近系统的基波频率，导致系统动态响应变差。提出了一种改进的电流控制策略，通过状态反馈控制的极点配置方法克服了这一难题，从而大大提高线性控制器的增益。电流控制器的设计以离散条件下的线性状态空间设计为原则，可使控制系统的动态响应和稳定性能更加优越，且系统具有更强的鲁棒性。最后，对设计结果进行了仿真。结果表明，基于状态反馈控制规律的极点配置法所设计的电流控制器比传统的PR设计方案具有更好的动态性能。

When AC current controller of low pulse inverter is designed by using the traditional control strategy, the controller system bandwidth usually closes fundamental frequency of the system to lead to the variation of dynamic system response. An improved current control strategy is presented. This problem is overcome by pole placement method of the state feedback control to greatly improve the linear controller gain. Taking the linear state space design under discrete conditions as the principle, the design of current controller can make dynamic response and stable performance of the control system more superior. And the system has stronger robustness. Finally the design results are simulated. The results show that devised current controller based on the pole placement method of the state feedback control law has better dynamic performance compared with that of the traditional PR design scheme.
