基于观测器的一类焊接系统鲁棒控制

Observer-based robust control of welding system

考虑一类焊接系统的鲁棒控制器的设计问题,针对焊接系统状态未知情形,给出了观测器设计方法。将李雅普诺夫稳定性理论和线性矩阵不等式技术相结合,实现鲁棒控制器设计。数值算例验证其可行性和有效性。

The problem of robust control for a class of welding system is considered.According to the case that state of the welding system is unknown,designing method of observer is given,and then Lyapunov theory and LMI technology are combined to gain robust controller.Numerical example verifies feasibility and effectiveness.
