| 中文摘要 |
| 给出多包描述约束系统的鲁棒调节器的一种新方法.现有的离线方案离线构造一系列的状态反馈控制律,其中每一个控制律是通过将无穷时域的控制输入固定为唯一的状态反馈控制律而得到的.而本文在优化较大椭圆内的控制律时,使下个时刻的状态进入临近的更小的椭圆———在较小的椭圆内部,相应的控制律序列作为局部控制器.因此,本文新方法相当于给出了变时域的预测控制器,可给出更优的控制作用.仿真例子说明了新方法的有效性. |
| 英文摘要 |
| A predictive controller achieving optimal control performance is investigated in this paper.Firstly,a set of state points is off-line selected.For each of these points,a control law and the corresponding ellipsoidal region of attraction are then calculated.In calculating the control law for a larger ellipsoid,it lets the state at the next time instant enter into the adjacent smaller ellipsoid,such that the performance cost optimization is based on a control law sequence.In this way,the controller obtained is horizon-varying.All the control laws are calculated via linear matrix inequality optimization problems.Besides,real time control law is on-line chosen as a linear interpolation of the off-line control laws,without any optimization problem involved.Finally,a simulation example shows the optimality improvement by this new technique. |
