The advantages of the proposed method are as follows: the system states will converge to zero at the desired finite time; the controlled system is globally robust against external disturbance and parameter variation; the system response can be analytically expressed; the system performance can be tuned by selecting different truncation function. Simulation results validate the effectiveness of the proposed method. %K 截断函数 有限时间 滑模控制 非线性< %K /br> %K truncation function finite-time sliding mode control nonlinear %U http://journal.nudt.edu.cn/gfkjdxxb/ch/reader/view_abstract.aspx?file_no=201802021&flag=1
