This brief is devoted to the power-constrained low-thrust optimal control problem (OCP). First, a general model for class of power constraints proposed by defining piecewise smooth function, which describes discontinuities system. Subsequently, recursive smoothing function generalized discontinuous terms leading family OCPs, whose solutions converge solution OCP. The distinguished feature that variations bound, caused constraints, are embedded into and retrieved gradually. Consequently,...
Reachability analysis is very useful and of great interest in various space missions. This correspondence proposes a method to compute the 2-D reachable set (RS) low-thrust spacecraft with bounded control limited fuel. For class smooth nonlinear affine-control systems, two-step solving procedure proposed solve boundary RSs. By constructing suitable homotopy, connection between homotopy path RSs built. The applied investigate orbital element RS spacecraft. In particular, both osculating mean...
