摘要
研究了一类基于扰动观测器的终端滑模混沌系统控制问题,利用扰动观测器估计了由系统中不确定项组成的混合扰动。通过构建终端滑模面保证了跟踪误差在有限时间内到达原点。运用Lyapunov函数证明了所设计控制方法能够实现误差系统稳定的结论,通过数值仿真证明了方法的有效性。
A class of terminal sliding mode chaotic system control problem based on disturbance observer is studied,and a mixed disturbance composed of uncertain terms in the system is estimated by using the disturbance observer.By constructing a terminal sliding surface,the tracking error is ensured to reach the origin within a finite time.The Lyapunov function is used to prove that the designed control method can achieve stable error systems,and the effectiveness of the method is demonstrated through numerical simulation.
