摘要
针对不确定SISO二阶系统中存在不确定参数、扰动等影响,研究非奇异快速终端滑模控制算法,设计控制器,理论上证明了系统的稳定性和输出误差的有限时间收敛,与采用线性滑模面的滑模控制方法相比,该方法提高了系统的响应性能。最后通过仿真证明了该方法的有效性。
The approach of nonsingular fast terminal sliding mode control is researched and the controller for second order system with uncertain parameters and load disturbance is designed.The close-loop stability of the system and the finite-time convergence of the trajectory tracking error are proved.The system performance is improved in comparison with the sliding mode control based on linear sliding mode.Finally,the effectiveness of proposed method is validated by simulation.
