使用优化约束收紧的计算高效鲁棒MPC

Computationally efficient robust MPC using optimized constraint tightening

Anilkumar Parsi, Panagiotis Anagnostaras, Andrea Iannelli, Roy S. Smith

摘要:

针对受有界附加扰动影响的线性定常系统,提出了一种鲁棒模型预测控制(MPC)方法。的主要贡献是离线设计的干扰仿射反馈增益,由此产生的约束收紧最小化。这是通过将约束收紧问题公式化为以反馈项为变量的凸优化问题来实现的。所得到的MPC控制器具有名义MPC的计算复杂度,并保证递归的可行性,稳定性和约束满足。所提出的方法相比,现有的强大的MPC方法的优点是使用数值例子证明。

英文摘要:

A robust model predictive control (MPC) method is presented for linear, time-invariant systems affected by bounded additive disturbances. The main contribution is the offline design of a disturbance-affine feedback gain whereby the resulting constraint tightening is minimized. This is achieved by formulating the constraint tightening problem as a convex optimization problem with the feedback term as a variable. The resulting MPC controller has the computational complexity of nominal MPC, and guarantees recursive feasibility, stability and constraint satisfaction. The advantages of the proposed approach compared to existing robust MPC methods are demonstrated using numerical examples.
