研究了一类具有外部干扰和非线性输入的不确定统一混沌系统的渐近稳定问题。利用滑模控风电场接入IE制技术,给出了一种新的切换面和滑模控制器设计方法。该方法能使状态空间任一点出发的运动都在有限时间内到达滑动模态,并沿切换面渐近到达原点。所设计的控制器既能使系统稳定性增强,又能降低控制器参数设计的保守性。最后,基于Matlab软件对Lorenz系统进行数值模拟,验证了该滑模控制方法的有效性。
The asymptotic stability of a class of uncertain unified chaotic systems with external disturbances and nonlinear inputs is investigated. Using sliding mode control wind farm access IE system technology, a new design method of switch face and sliding mode controller is given. This method can make the motion starting at any point in the state space reach the sliding mode within a limited time and arrive asymptotically along the switching plane. The design of the controller not only makes the system more stable, but also reduces the conservativeness of the controller parameter design. Finally, the numerical simulation of Lorenz system based on Matlab software verifies the validity of the sliding mode control method.
