AI 中文摘要
我们提出了CS-P2L,这是一个将协方差控制(CS)与选学(P2L)元算法相结合的框架,用于在高保真随机模拟器上进行认证控制器合成。该方法在模拟器展开中迭代评估策略,利用最坏情况违规收紧代理约束,并在给定置信水平下提供基于压缩的真实违规概率的概率保证。在具有不确定重力的航天器动力下降问题上,CS-P2L通过600次展开认证了4.9%的违规界限,而单独的协方差控制将违规率低估了约两倍。
英文摘要
We present CS-P2L, a framework coupling covariance steering (CS) with the Pick-to-Learn (P2L) meta-algorithm for certified controller synthesis over high-fidelity stochastic simulators. The method iteratively evaluates policies on simulator rollouts, tightens surrogate constraints using the worst-case violations, and provides compression-based probabilistic guarantees on the true violation probability given a confidence level. On a spacecraft powered-descent problem with uncertain gravity, CS-P2L certifies a violation bound of 4.9\% with 600 rollouts, whereas standalone covariance steering underestimates the violation rate by roughly a factor of two.
