基于CBF控制器的多智能体系统的碰撞避免和活性

Collision Avoidance and Liveness of Multi-agent Systems with CBF-based Controllers

Mrdjan Jankovic, Mario Santillo

摘要:

在本文中,我们考虑使用控制障碍函数(CBF)避免碰撞的多智能体导航。在非通信代理的情况下,我们考虑安全保证水平和活性之间的权衡-在短时间内到达目的地而不需要大的弯路或交通堵塞的能力。我们比较了几个CBF为基础的驾驶政策对基准建立的集中式控制器,需要通信。正在比较的策略之一(CCS 2)是新的,并且跨越了仅可用本地控制的策略与更复杂的预测-校正冲突避免(PCCA)策略之间的空间,该PCCA策略基于观察到的行为调整每个人的控制动作的本地副本。本文为集中式、PCCA和CCS2策略建立了可行性。蒙特卡洛模拟表明,分散的,只有主机的控制策略相比,在计算中使用所有的控制输入,PCCA政策表现同样好,集中式相比,缺乏活性,即使它是分散的。

英文摘要:

In this paper we consider multi-agent navigation with collision avoidance using Control Barrier Functions (CBF). In the case of non-communicating agents, we consider trade-offs between level of safety guarantee and liveness - the ability to reach destination in short time without large detours or gridlock. We compare several CBF-based driving policies against the benchmark established by the Centralized controller that requires communication. One of the policies (CCS2) being compared is new and straddles the space between policies with only local control available and a more complex Predictor-Corrector for Collision Avoidance (PCCA) policy that adjusts local copies of everyone's control actions based on observed behavior. The paper establishes feasibility for the Centralized, PCCA and CCS2 policies. Monte Carlo simulations show that decentralized, host-only control policies lack liveness compared to the ones that use all the control inputs in calculations and that the PCCA policy performs equally well as the Centralized, even though it is decentralized.
