摘要:

我们提出了一种计算非线性离散时间控制系统后向可达集的方法,该方法基于动态博弈框架,利用对称性在低维空间中简化动态规划迭代,无需对状态更新方程进行代数操作。通过计算两辆Dubins车辆的六维达-避博弈的后向可达集,展示了方法的有效性。

英文摘要:

We present a method of computing backward reachable sets for nonlinear discrete-time control systems possessing continuous symmetries. The starting point is a dynamic game formulation of reachability analysis where control inputs aim to maintain the state variables within a target tube despite disturbances. Our method exploits symmetry to compute the reachable sets in a lower-dimensional space, enabling a significant computational speedup. To achieve this, we present a general method for symmetry reduction based on the Cartan frame, which simplifies the dynamic programming iteration without algebraic manipulation of the state update equations. We illustrate the results by computing a backward reachable set for a six-dimensional reach-avoid game of two Dubins vehicles.
