中文摘要	介绍了背靠背四象限变流器控制系统的设计方案。整个控制系统由上层功率控制策略和底层PWM控制构成。在建立了背靠背四象限变流器在两相同步旋转坐标系下动态模型的基础上,提出了基于反馈线性化的非线性解耦控制器,并为背靠背两侧变流器分别设计了定直流电压和定有功、无功功率控制器。底层控制方面,设计了基于FPGA的空间矢量调制脉冲发生器。FPGA接收来自DSP的PWM控制参数,用于脉冲信号发生。最后给出了整个控制系统的硬件结构,并在30kVA/380V背靠背物理样机上进行了试验验证。; The design of control system for back-to-back four-quadrant converter is presented.The whole control sys-tem was made up of upper power control and bottom PWM control.The state space model of the back-to-back four-quadrant converter was developed in the synchronous orthogonal d,q frame.Based on the developed model,a nonlinear decoupled controller was designed using the linearization of feedback.For one side of the back-to-back converter system,the nonlinear controller was used to control the DC-link voltage.For another side,the nonlinear controller was used to control the trans-ferred active and reactive power.A FPGA-based realization of the space vector modulation(SVM) was presented.Cooper-ated with the digital signal processor(DSP),the FPGA was dedicated to generating PWM gating signals.The developed control system was verified using the experimental results on a 30kVA/380V back-to-back prototype system.
