状态饱和奇异离散线性系统的稳定性分析与控制律综合
Stability Analysis and Controller Synthesis for Singular Discrete Linear Systems with State Saturation
摘要
Abstract
The problem of stability analysis and state feedback controller synthesis tor singular discrete linear systems with state saturation is studied.By introducing a free matrix whose infinity norm is less than or equal to 1,the state variables under saturation constraint are confined in a convex hull whose vertexes are associated with this free matrix.Based on this,the original stability problem of singular discrete systems with state saturation nonlinearity is transformed into the robust stability analysis problem of linear singular discrete systems with polytopic type uncertain parameters.With the introduction of a free matrix to draw the relationship between algebraic subsystem variables and difference subsystem variables,a sufficient criterion for discrete linear singular systems with state saturation to be regular,causal and asymptotically stable,is obtained in terms of matrix inequalities.The corresponding state feedback control law synthesis algorithm is also given.The obtained stability criterion and controller design algorithm are given in terms of matrix inequalities that can be solved using the presented iterative linear matrix inequality algorithm.Numerical examples are used to show that the presented method is applicable and effective.关键词
