将伪谱最优控制理论与航天飞行结合，实现嵌入式平台的高效控制。
A Review of Pseudospectral Optimal Control: From Theory to Flight
- 融合伪谱理论与最优控制，构建可落地的飞行控制方法
- 2011年首次在NASA航天器上实现嵌入式部署
- 适合航空航天与自主系统领域的研究者参考
最优控制的定义域是Sobolev空间，伪谱理论的定义域同样是Sobolev空间，因此将二者结合构建‘伪谱最优控制理论’具有天然合理性。本文回顾了该理论中对飞行任务成功至关重要的关键理论成果，并讨论了其在NASA航天器上的实际部署细节。同时介绍了理论与实践中的新兴趋势与技术进展。自2011年伪谱最优控制首次在嵌入式平台实现以来，正改变着我们解决航空航天与自主系统中复杂控制问题的方式。
原文摘要 · Abstract (English)
The home space for optimal control is a Sobolev space. The home space for pseudospectral theory is also a Sobolev space. It thus seems natural to combine pseudospectral theory with optimal control theory and construct ``pseudospectral optimal control theory,'' a term coined by Ross. In this paper, we review key theoretical results in pseudospectral optimal control that have proven to be critical for a successful flight. Implementation details of flight demonstrations onboard NASA spacecraft are discussed along with emerging trends and techniques in both theory and practice. The 2011 launch of pseudospectral optimal control in embedded platforms is changing the way in which we see solutions to challenging control problems in aerospace and autonomous systems.
