优化方法:对于求解的规划问题,它能保证连续求出来后,就是满足约束的,连续空间下的最优解。但是对于路径规划来说,约束基本都是非凸的,这就导致直接加障碍物约束,又会出现求解难,求解时间不确定等因素。 基于以上优化问题的特点,有两种思路: 将障碍物约束加入到优化问题中 原优化问题先不考虑障碍物,求解出最优解后...

Meanwhile, the discrete-time exponential control barrier functions are adopted to address the issue of state constraints. Moreover, the convergence of the proposed algorithm is proven in theory. Then, the system dynamics, the control policies and the value function are approximated by the three-...
To address the challenge of ensuring constraint satisfaction while leveraging the benefits of learning-based control, the field of safe learning has gained prominence and several safety frameworks have been proposed [16], [17], employing various approaches like control barrier functions [18], Hamilton...

总结一下,基于可达性的Scenery可以学到最大的EFR,而其他诸如Control Barrier Function(CBF)则不保证学到最大的EFR。而且基于可达性的ACS算法还对于Model Mismatch和外界扰动具有良好的鲁棒性。然而,其缺点也存在,即当动作空间不是离散或者控制仿射系统时,需要使用数值优化的方法来求解,实际上需要设置两个策略网络,一个...
