提出了一种新的线性约束系统预测控制方案,该方案利用乘法器的交替方向法进行在线优化。与现有的基于admm的模型预测控制(MPC)相比,我们在每个时间步只考虑一个admm迭代。由此产生的实时ADMM方案是为嵌入式和快速MPC实现量身定制的。与现有基于实时迭代的MPC方案的主要区别在于,所提出的控制器允许包含系统的状态和输入约束。本文推导了闭环系统的动力学特性,确定了实时ADMM的重要参数,并将其性能与经典MPC进行了比较。
We present a novel predictive control scheme for linear constrained systems that uses the alternating direction method of multipliers (ADMM) for online optimization. In contrast to existing works on ADMM-based model predictive control (MPC), we only consider a single ADMM-iteration in every time step. The resulting real-time ADMM scheme is tailored for embedded and fast MPC implementations. The main difference to existing MPC schemes based on real-time iterations is that the proposed controller allows to include state and input constraints of the system. The paper derives the dynamics of the resulting closed-loop system, identifies important parameters of the real-time ADMM, and compares its performance to classical MPC.
