摘要:

安全地学习和执行最优控制策略的能力对于实现复杂的自主性是至关重要的,特别是在任务重启不可用和/或系统是安全关键的情况下。安全要求通常用状态和/或控制约束来表示。诸如障碍变换和控制障碍函数的方法已经成功地与基于模型的强化学习结合用于在状态约束下的系统中的安全学习,以学习最优控制策略。然而,现有的基于障碍的安全学习方法依赖于完整的状态反馈。针对一类状态部分可观测的安全关键系统,提出了一种基于输出反馈安全模型的强化学习方法,该方法利用一种新的动态状态估计器实现同时学习和控制.

英文摘要:

The ability to learn and execute optimal control policies safely is critical to realization of complex autonomy, especially where task restarts are not available and/or the systems are safety-critical. Safety requirements are often expressed in terms of state and/or control constraints. Methods such as barrier transformation and control barrier functions have been successfully used, in conjunction with model-based reinforcement learning, for safe learning in systems under state constraints, to learn the optimal control policy. However, existing barrier-based safe learning methods rely on full state feedback. In this paper, an output-feedback safe model-based reinforcement learning technique is developed that utilizes a novel dynamic state estimator to implement simultaneous learning and control for a class of safety-critical systems with partially observable state.
