摘要:
针对受外界扰动和参数不确定性影响的线性系统,同时考虑其暂态性能和稳态性能,提出基于混合稳定的鲁棒H∞控制概念和控制方法.给出闭环系统混合稳定且抑制外部扰动对被控输出影响的充分条件,并将这些条件转化为线性矩阵不等式约束.所设计的是一个关于时间连续的H∞混合镇定控制器,简化了设计过程,避免控制器切换导致的抖振.仿真结果表明:在外界扰动和参数不确定影响的情况下,该控制方法达到预期的暂态性能和稳态性能的要求,且有效抑制了干扰对系统状态的影响.
Abstract:
To guarantee both the transient and steady performances of a linear system with uncertainties and disturbances, a new control method called mixed-stability-based H∞ stabilization is proposed. The solvable conditions of mixed-stability-based H∞ stabilization are presented by using the linear matrix inequalities. The mixed-stability-based H∞ stabilization controller given in this paper is continuous in time domain, thus simplifies the design process and avoids the potential chattering. Finally, a numerical simulation is conducted to demonstrate the effectiveness and feasibility of the proposed method.
