The D-Wave quantum annealer has emerged as a novel computational architecture
that is attracting significant interest, but there have been only a few
practical algorithms exploiting the power of quantum annealers. Here we present
a model predictive control (MPC) algorithm using a quantum annealer for a
system allowing a finite number of input values. Such an MPC problem is
classified as a non-deterministic polynomial-time-hard combinatorial problem,
and thus real-time sequential optimization is difficult to obtain with
conventional computational systems. We circumvent this difficulty by converting
the original MPC problem into a quadratic unconstrained binary optimization
problem, which is then solved by the D-Wave quantum annealer. Two practical
applications, namely stabilization of a spring-mass-damper system and dynamic
audio quantization, are demonstrated. For both, the D-Wave method exhibits
better performance than the classical simulated annealing method. Our results
suggest new applications of quantum annealers in the direction of dynamic
control problems.

使用 D-Wave 量子退火器对有限输入系统进行模型预测控制
D-Wave 量子退火器已成为一种新的计算架构,引起了极大的兴趣,但只有少数实用算法利用了量子退火器的强大功能。在这里,我们提出了一种模型预测控制 (MPC) 算法,该算法将量子退火器用于允许有限数量输入值的系统。这种 MPC 问题被归类为非确定性多项式-时间-困难组合问题,因此传统计算系统难以获得实时顺序优化。我们通过将原始 MPC 问题转换为二次无约束二元优化问题来规避这一困难,然后由 D-Wave 量子退火器解决。两个实际应用,即弹簧质量阻尼器系统的稳定和动态音频量化,被证明。对于这两种方法,D-Wave 方法表现出比经典模拟退火方法更好的性能。我们的结果表明量子退火器在动态控制问题方向上的新应用。
