摘　　要：RST(多项式)控制是一种基于极点配置的两自由度控制方法,相比传统控制增加了一个自由度,实现了调节特性与跟踪特性的独立设计。文章介绍了在离散域设计的单相逆变器电压和电流环RST控制器,将谐振项引入到控制器参数计算中,在静止坐标系下实现了对正弦参考信号的无静差调节;研究了参考信号频率波动以及控制对象参数波动下RST控制器性能。通过在RST控制器多项式S中附加积分项,大大提高了控制系统的鲁棒性。实验结果表明,采用RST控制器的单相逆变器频率适应性强、鲁棒性好。RST（polynomial） controller is a method with two degrees of freedom based on pole placement, which is one more degree comparing with the traditional control and can realize regulation performance and tracking performance. It studied single-phase inverter voltage and a current-loop RST controller in the discrete domain, and realized static error modulation in stationary frame by addition of resonant term. The RST controller＇s performance was analyzed under the influences of reference frequency variation and parameters variation of the control object. The robustness of the control system was enhanced by imposing additional integral in the polynomials S of RSI controller. The experimental results confirm that the single phase inverter with RSI controller has good frequency adaptability and robustness.
