研究了带有预见信息的线性离散时间系统的状态观测器,并将其应用到预见控制系统.为了满足设计观测器的需要,首先导出了包含可预见的目标值信号和干扰信号的扩大误差系统,并由此得到最优预见控制器.在设计状态观测器时,通过改写输出方程充分利用了可预见的目标值信号和干扰信号.设计的状态观测器针对原系统是全维观测器,而针对扩大误差系统则是降维观测器.最后通过数值仿真证明了所设计的状态观测器的有效性.
The state observer of linear discrete-time system with predictive information is studied and applied to the predictive control system.In order to meet the needs of the design observer, an extended error system including predictive target value signal and interfering signal is first derived , And the optimal predictive controller is obtained.In the design of state observer, the predictable target value signal and jamming signal are fully utilized by rewriting the output equation.The designed state observer is a full-dimensional observer for the original system, In order to enlarge the error system, it is a reduced-dimensional observer. Finally, the validity of the designed state observer is proved by numerical simulation.
