Embodiment Construction
[0048] The present invention will be further described below in conjunction with accompanying drawing:
[0049] Such as figure 1 As shown, the global optimization method of planetary hybrid power system with constrained terminal state is characterized by:
[0050] The first step is to determine the global optimization objective function and constraints of the planetary hybrid power system: the global optimization problem of the planetary hybrid power system is expressed as:
[0051]
[0052]
[0053] In formula (1), J(u(t)) is the cost function of the system, which can be expressed as the instantaneous cost L(x(t),u(t),t) at each moment in the whole working condition for the hybrid system Integral, plus a penalty function G(x(t) based on the termination state f )),as follows:
[0054]
[0055] The configuration of the planetary hybrid power system of this embodiment is as follows figure 2 As shown, the cost function and constraints of the planetary hybrid power s...
