摘要
针对一类参数未知的线性系统,为了设计出一种能提高系统动态性能的控制律,通过构造分数维的Lyapunov函数,设计出了新的模型参考自适应控制系统,进而证明了该闭环系统是稳定的.仿真实验验证了该闭环系统具有调节时间短、超调量小等更好的动态性能.
This paper studies a novel adaptive control strategy for a linear system with unknown parameters. To design a control law with perfective dynamic performance, a new model reference adaptive control system has been designed by constructing a fractional-order Lyapunov function, with the stability of the closed-loop system proved. An example＇s simulation shows that the closed-loop system has the better dynamic performance such as less regulating time and less overshoot than by the traditional method.
