| 中文摘要 |
| 单相可再生能源并网发电系统是一非线性系统,受电网和环境的影响,系统存在较强的外部干扰和非线性不确定因素.针对系统的工作特点,采用自抗扰控制技术来实现对系统的有效控制.系统利用自抗扰控制器(ADRC)的扩张状态观测器,来对系统模型中的不确定因素和外扰进行动态观测,使系统对扰动具有很好的适应能力.并在系统的扩张状态观测器和非线性状态误差控制器中引入非线性幂指数函数,使系统运算变得更加简单.仿真结果表明所设计的控制器具有良好的动态性能和较强的鲁棒性,即本文所设计的系统是可行的. |
| 英文摘要 |
| Renewable energy generation system connected to the single-phase grid is nonlinear.Affected by grid and environment,the strong disturbance exists.To deal with this characteristics,the auto-disturbances rejection control(ADRC) is used to improve the system's performance.Based on ADRC extended state observer(ESO) to get the model uncertainty and external interference of the system,the system shows good adaptability to noise and model uncertainty.A nonlinear exponential function is applied to ESO and nonlinear state error feedback(NLSEF) controller,and it makes the system realize easier operation.Simulation tests show that the system has good robustness and dynamic performance and the system is feasible. |
