摘　　要：基于微分几何方法提出了关于双向矩阵变换器动态特性的分析方法,针对不同的输出控制量,得到电路的内动态方程,判断电路内动态的稳定性,由此决定采用控制策略时参数的选择。分析结果表明该方法能够有效分析电路的动态特性。同时根据分析结果采用输入输出线性化方法推导出了系统的输入输出控制律。仿真结果表明该方案能够很好地保持控制系统的稳态性。Based on differential geometry, a novel dynamic characteristic analysis method for a bidirectional matrix converter is proposed. The internal dynamics and stability of the system and dynamic characteristic are achieved by the different outputs. And thus the parameters of the control strategies are given. The results show that the method can prove the efficiency of the analysis of the circuits. In consideration of the output parameters of the circuit, a control scheme based on input-output linearization theory is proposed. The validity of the analysis law with excellent steady-state and dynamic characteristics is verified by the simulation results.
