| 摘要: |
| 传统的等速趋近律滑模控制器在控制移相全桥变换器时，会出现趋近时间长、抖振严重的问题，为此提出了一种优化的等速趋近律控制方法，用来解决等速趋近率的不足;同时，还增加了电感电流状态变量，给出了移相全桥变换器数学模型;最后，利用优化的等速趋近律对移相全桥变换器滑模控制器进行了设计，并且与PI控制器、等速趋近律控制器相比较;仿真结果表明:所提的控制方法对于系统的静态、动态特性与鲁棒性都有所改善。 |

| Abstract: |
| There are the problems in long approaching time and serious chattering when traditional isotropic approaching law sliding mode controller is controlling phase shifted full bridge converter, as a result, an optimized isotropic approaching law control method is proposed in order to solve the deficiency of the isotropic approaching rate, meanwhile, the state variable of inductor current is added, and the mathematical model of the phase shifted full bridge converter is given. Finally, the optimized isotropic approaching law is used to design phase shifted full bridge converter sliding mode controller, which is compared with PI controller and isotropic approaching law controller. Simulation results show that the proposed method improves static, dynamic and robust performance of the system. |
