基于稀疏扩展ADMM算法的嵌入式系统跟踪模型预测控制

Implementation of model predictive control for tracking in embedded systems using a sparse extended ADMM algorithm

Pablo Krupa, Ignacio Alvarado, Daniel Limon, Teodoro Alamo

摘要:

本文提出了一种稀疏的,低内存占用的优化算法,用于在嵌入式系统中实现模型预测控制(MPC)的跟踪制定。该MPC公式与标准MPC公式相比具有几个优点,例如增加的吸引域和保证的递归可行性,即使在突然的参考变化的情况下。然而,这是以向MPC的优化问题添加少量决策变量为代价的,这使其矩阵的结构复杂化。我们提出了一个稀疏优化算法,基于扩展的交替方向的乘法器,利用这种特殊的MPC制定的结构。我们描述了控制器的制定和详细说明其结构是如何利用上述优化算法。我们展示了闭环模拟比较建议的求解器对其他求解器和方法从文献。

英文摘要:

This article presents a sparse, low-memory footprint optimization algorithm for the implementation of the model predictive control (MPC) for tracking formulation in embedded systems. This MPC formulation has several advantages over standard MPC formulations, such as an increased domain of attraction and guaranteed recursive feasibility even in the event of a sudden reference change. However, this comes at the expense of the addition of a small amount of decision variables to the MPC's optimization problem that complicates the structure of its matrices. We propose a sparse optimization algorithm, based on an extension of the alternating direction method of multipliers, that exploits the structure of this particular MPC formulation. We describe the controller formulation and detail how its structure is exploited by means of the aforementioned optimization algorithm. We show closed-loop simulations comparing the proposed solver against other solvers and approaches from the literature.
