| 中文摘要 |
| 针对开环稳定的单变量系统, 提出了一种简单可行的三角化脉冲响应近似模型, 改进了A。str¨om的简化模型. 进而设计鲁棒扩展时域预测控制器. 此控制器只需辨识一个脉冲响应值即可, 大大减少了计算量. 同时给出了在模型失配情况下保证闭环系统全局渐近稳定的预报长度范围和模型失配上限值. 仿真结果表明此方法的有效性和鲁棒性. |
| 英文摘要 |
| In this paper a simplified impulse response model is presented for approximating a stable system to improve \{A。strm\} and Lu's methods. An extended horizon predictive controller can be designed based on this approximation model. Only one parameter should be estimated and much more computational effort can be reduced. Under model plant mismatch the robustly asymptotic stability and global convergence of the resulting closed loop system are guaranteed by selecting proper prediction horizon. Simulations show that the new controller is effective and works well even in time varying and unknown constant disturbances environment. |
