| 中文摘要 |
| 针对一类含有噪声干扰和非线性参数的高次随机非线性系统, 研究了依概率全局自适应稳定问题. 在噪声的协方差未知的情况下, 利用自适应增加幂积分方法和参数分离技术, 提出了一种反馈占优设计方法并构造了一个光滑自适应控制器. 该控制器能保证闭环系统依概率全局稳定, 并且系统的状态几乎必然收敛到零. 仿真例子验证了控制方案的有效性. |
| 英文摘要 |
| The adaptive global stabilization problem is studied for a class of high-order stochastic nonlinear systems driven by noise of unknown covariance and with nonlinear parameterization. Based on the method of adaptive adding a power integrator and using the technique of parameter separation, a feedback domination design approach is presented and a smooth adaptive controller is constructed which ensures for the closed-loop system the global stability in probability, and the states can be regulated to zero almost surely. A simulation example is given to illustrate the effectiveness of the control scheme. |
