| 中文摘要 |
| 本文的目的是针对一类带有不确定性的单输入单输出的仿射非线性系统, 设计一种非线性预测控制器. 用反步设计思想获得具有待定参数的控制器表达式, 然后用预测控制在线优化获得控制器的参数. 用这种方法设计的控制器更易使闭环系统稳定, 且闭环系统具有良好的动态特性. 连续发酵过程的仿真结果也验证了控制器是有效的. |
| 英文摘要 |
| The purpose of this paper is to design a robust nonlinear model predictive controller for a class of single input single output affine nonlinear systems with uncertainty. The controller expression with undetermined parameters can be acquired by using backstepping design idea, and the controller parameters are optimized online by using model predictive control. By using controller proposed in this paper, not only the stability of the closed loop system can be acquired more easily but also the dynamic behavior of the closed loop system is good. The simulation of a continuous fermenter process also shows that the controller is valid. |
