| 中文摘要 |
| 针对一类不确定非线性系统,
基于变结构控制原理,

提出一种具有模糊监督控制器的积分变结构间接自适应控制方案.
该方案通过监督控制器保证闭环系统所有信号有界. 进一步,
通过引入最优逼近误差的自适应补偿项来消除建模误差的影响.
理论分析证明了跟踪误差收敛到零. 仿真结果表明了该方法的有效性. |
| 英文摘要 |
| A new integral variable structure
indirect adaptive control scheme with fuzzy supervisory controller
is developed for a class of uncertain nonlinear systems in this
paper. The design is based on the principle of variable structure
control. The fuzzy systems with nonlinear adjustable parameters are used to
approximate unknown plant functions. With the help of a supervisory controller,
the resulting closed-loop system is globally stable in the sense that
all signals involved are uniformly bounded. Furthermore, the adaptive
compensation term of the optimal approximation error is introduced to
minimize the effects of modeling error. By theoretical analysis,
it is shown that the tracking error converges to zero. Finally,
simulation results demonstrate the effectiveness of the approach.
