| 中文摘要 |
| 针对多变量饱和线性系统的时变参考输入跟踪问题, 研究了一种组合非线性输出反馈控制器的设计方法. 基于原始的组合非线性反馈理论, 构造了全阶和降阶输出反馈控制器. 控制器由线性输出反馈项和非线性反馈项组成, 使得闭环系统在包含于吸引域的不变集内渐近稳定. 除了能够跟踪时变参考输入外, 系统还具有良好的动态性能. 仿真结果说明了所开发控制器的有效性. |
| 英文摘要 |
| A new composite nonlinear output feedback controller is proposed to track the time-varying reference inputs for multivariable linear systems with input saturation. Based on the original composite nonlinear feedback theory, we
respectively developed the full-order and the reduced-order output feedback controllers. Both controllers consist of linear output feedback and nonlinear feedback, resulting in a closed-loop system with asymptotic stability in the invariant set inside the domain of attraction. Besides the guaranteed ability of tracking time-varying reference inputs, the systems have an excellent transient performance. Simulation results demonstrate the feasibility of the proposed controller. |
