摘　　要：针对带有界干扰的多胞描述约束LPV系统,提出一种鲁棒预测控制综合方法,设计保证系统闭环稳定的状态反馈控制器。为减少计算的复杂性,采用线性矩阵不等式求解预测控制无穷时域最小-最大优化问题,获得状态反馈控制律,将该控制率施加到系统,证明了算法的可行性和系统的闭环稳定性。通过仿真实验验证了算法有效性。Consider a kind of polytopic described LPV system with bounded disturbances,a synthesis of robust model predictive control is proposed,which adopts a category of state feedback controller. In order to reduce the computational complexity,a stability guaranteed state feedback control law is achieved by solving the min-max optimization problem of the worst-case infinite time horizon cost function. And the proposed robust MPC algorithm can asymptotically stabilized the state-delayed LPV system. And an example proves the effectiveness of the algorithm.
