摘要
对单机无穷大系统进行非线性H∞励磁控制器的设计。应用直接反馈线性化方法,直接指定虚拟控制量,简化了计算;采用△d、△w、△Pe和△Vt的积分量为状态变量,以同时改善电力系统的稳定性和调压精度;应用H∞控制理论和MATLAB的m -综合工具箱完成权函数的优化,直接解决鲁棒控制设计;对控制律进行实用化处理,并利用Powersys工具箱进行了仿真分析,收到了较好的效果。
A design of nonlinear H∞excitation controller for single-machine infinite-bus power system is proposed in the paper. Applying direct feed back linearization and directlyassigning virtual control variable, the calculation is simplified. △d, △w, △Pe and the integrated quantity of △Vt is used as state variable to simultaneously improve power system stability and voltage regulation accuracy. The optimization of power function is implemented by H∞control theory and m-synthesis toolbox in Matlab and the design of non-linear robust control is performed. The engineering practicality of the control rule is carried out and is simulated by the Powersys toolbox in Matlab.
