具有极点约束的焊接系统非脆弱控制

Non-fragile control of welding system with pole constraints

研究了一类焊接系统的非脆弱控制问题。首先将焊接系统等效为不确定采样系统,然后将极点约束理论与线性矩阵不等式理论相结合,给出非脆弱控制器的存在条件和控制器设计方法。最后,通过数值算例验证了控制算法的可行性和有效性。

Non-fragile control of a class of welding system is proposed. Firstly welding system is equivalent to uncertain sampled-data system, and then pole constrains and linear matrix inequalities are combined to give the exist condition of non-fragile controller and design method. Finally, numerical example verifies feasible and effective.
