摘要
对于含有未建模动态的输入受限离散时间线性系统 ,当系统状态不可测时 ,提出一种基于状态观测器的鲁棒模型预测控制算法。该算法采用双模控制结构 ,将不变椭圆集同时应用于估计状态方程和误差方程 ,保证算法的稳定性和可行性 。
A robust model predictive control algorithm is presented for linear discrete-time system with input constraint and unmodelling dynamics when the state of controlled system are unmeasurable. Using dual mode control structure, the ellipsoid invariant set is applied to estimate state and states estimation error to guarantee the stability and feasibility of the algorithm. The conditions of stability and feasibility of system are presented as well.
