| 中文摘要 |
| 并联混合有源滤波器(SHAPF)的控制策略是决定其稳定性和谐波治理效果的关键因素之一, 利用SHAPF自身的无源性设计控制器可以取得比常规控制器更好的控制效果. 首先建立了SHAPF端口受控哈密顿系统模型, 然后基于互联和阻尼配置无源控制方法, 提出了一种新的SHAPF非线性控制策略, 从理论上保证了闭环系统的渐进稳定. 最后仿真实验证明了该控制策略能够有效消除电网中的谐波电流, 与传统线性二次型调节器(LQR)相比, 该控制策略具有更好的稳态补偿效果和对负载变化的干扰抑制能力. |
| 英文摘要 |
| A good control strategy is crucial to the stability and desired performance of the shunt hybrid active power filter (SHAPF). Based on the passivity of the SHAPF, a nonlinear controller is designed that outperforms the traditional controllers. Firstly, a port-controlled Hamiltonian system model is built for the SHAPF, and then a novel control strategy of the SHAPF is developed by using the passive controller design method through interconnection and damping- assignment.
Theoretically, the proposed control strategy can asymptotically stabilize the close-loop system. Simulation results show higher harmonic elimination and robust performances are achieved in comparison with the linear quadratic regulator (LQR). |
