| 矩阵变换器无中间直流环节, 易受电网扰动和负载扰动的影响. 针对这一问题, 本文设计了矩阵变换器输入侧无源性控制器以改善控制系统特性. 首先, 在直–交坐标系下建立输入侧的端口受控耗散哈密尔顿(port-controlled Hamiltonian with dissipation, PCHD)算子模型. 然后, 设计了基于互联和阻尼配置的无源性控制器, 用来实现对
输入电流快速准确的跟踪. 重新配置了系统的平衡点, 通过注入阻尼提高系统的收敛速度, 并从理论上对闭环系统的渐进稳定性进行了分析. 仿真结果表明, 系统在非正常工况下仍能保证输入电流为正弦, 相比传统偏差修正法, 该控制策略具有更好的动态性能和抗干扰能力. |

| Because there is no intermediate direct current loop in matrix converter (MC), MC is sensitive to disturbances in grid voltage and from the load. To deal with this problem, we develop a passivity-based controller in the input side to improve the characteristics of the MC. First, the model of the port-controlled Hamiltonian with dissipation (PCHD) on the input side is built in synchronous d-q coordinates. Then, the passivity controller is redesigned based on the interconnection and the damping assignment (IDA--PBC), for realizing the fast and accurate tracking of the input current. The equilibrium point of the system is reassigned and a damping injection controller is proposed to improve the convergence rate of the system. Theoretically, the proposed control strategy can asymptotically stabilize the close-loop system. Simulation results shows that the input current maintains the sinusoidal waveform under abnormal conditions, and better dynamic performance and higher robustness are achieved in comparison with the traditional error-correction methods. |
