基于目标全息反馈的励磁滑模控制

Excitation sliding mode control based on objective holographic feedback

应用目标全息反馈法将系统中非线性因素转换到含有控制输入的状态方程中,转换后的系统中非线性因素转移到最后一阶方程中,然后使用最优反馈法来求得系统的滑模切换面的行向量。为抑制滑模控制器可能出现的抖振现象,故用饱和函数取代了符号函数。最后MATLAB的仿真结果证明了该方法的有效性。

By applying objective holographic feedback,the non-linear factor in the system is transformed into the state equation with control input and then the last equation.The row vector of the switching surface of the sliding mode is worked out by the optimal feedback method.Sign function is replaced by saturation function in order to restrain the buffeting of sliding mode controller.The simulation result by MATLAB proves the effectiveness of this method.
