线性连续系统混沌跟踪控制的T-S模型方法

The tracking chaos control of a linear continuous system—T-S model method

针对连续时间稳定线性系统的混沌跟踪控制问题,采用T-S模糊模型表示的非线性混沌系统为参考模型,通过引入跟踪控制器,实现了连续时间稳定线性系统渐近跟踪某混沌系统,使整个系统具有期望的混沌行为。控制器的设计不需要精确对消条件,提高了控制器设计的灵活性,使之更易于实际应用。仿真研究表明,通过优化控制器参数减少了跟踪误差,提高了控制精确度。

For the tracking chaos problem of a continuous-time stable linear system, the T-S fuzzy model of nonlinear chaos system is used as reference model, and tracking controller is designed. It is realized successfully that a continuous-time stable linear system asymptotically follows a chaos system and the whole system has desired chaotic performance. The condition of exact cancellation is not needed for designing controller; so the controller can be designed flexibly and easy to be used practically. The simulation shows that the tracking error is reduced by optimized parameters of the controller and a high precise control is got.
