一类波动方程的输出追踪问题的研究

The Output Tracking for a Class of Wave Equation

考虑了一类波动方程的输出追踪问题,其中参考信号为谐波信号,控制和性能输出是非同位的.首先通过输出设计了状态观测器,估计系统状态.然后利用估计的状态,设计控制器,使性能输出追踪到给定的参考信号,并保持闭环系统所有状态有界.

This paper considers the output tracking of a class of wave equations,in which the reference signal is a harmonic signal,the control and performance output are non-collocated. We first design the state observer in terms of the output to estimate the state of the system. Then by using the estimated state,the controller is designed to make the performance output to track the given reference signal and keep all states of the closed-loop system bounded.
