摘要:

随着自动化向速度越来越快的应用以及低功耗边缘设备扩展,模型预测控制等基于优化的控制算法面临特殊挑战。我们提出的机器学习辅助方法通过使用前馈神经网络降低在线优化的计算负担来解决这一问题。我们建议对问题预测时域的一部分进行近似,同时通过控制器中保留的优化部分维持安全保证——即约束满足。该方法在仿真中得到验证,结果表明计算效率有所提升,同时保持了各项保证和接近最优的性能。所提出的MPC方案可应用于广泛场景,包括机器人和计算资源有限的嵌入式应用等需要快速控制响应的场景。

英文摘要:

The expansion in automation of increasingly fast applications and low-power edge devices poses a particular challenge for optimization based control algorithms, like model predictive control. Our proposed machine-learning supported approach addresses this by utilizing a feed-forward neural network to reduce the computation load of the online-optimization. We propose approximating part of the problem horizon, while maintaining safety guarantees -- constraint satisfaction -- via the remaining optimization part of the controller. The approach is validated in simulation, demonstrating an improvement in computational efficiency, while maintaining guarantees and near-optimal performance. The proposed MPC scheme can be applied to a wide range of applications, including those requiring a rapid control response, such as robotics and embedded applications with limited computational resources.
