摘要
任何实际的系统均受到不同形式的限制,例如状态受限、输入饱和等.还有一种限制是传感器或执行机构数量的不足.文章主要研究了传感器和执行机构数量不足情况下的非线性系统有限时间控制问题.针对这类间题获得了有限时间镇定控制的设计方法,并讨论了相应的控制器的实施问题.通过对某Lorenz混沌系统的仿真应用模拟,验证了所提出设计方法的可行有效.
Any realistic system is restricted in one form or another. One of the restrictions is the lack of sensors and actuators. This paper addresses the problem of restricted control of nonlinear systems with a finite time approach. Important results are obtained on the design of controllers for stabilizing nonlinear systems in a finite time. Practical issues on control implementation are also discussed. The proposed design method is validated through its application to a Lorenz chaotic system.
