Cooperative game theory-based steering law design of a CMG system
نویسندگان
چکیده
Spacecraft require a large-angle manoeuvre when performing agile manoeuvring tasks, therefore control moment gyroscope (CMG) is employed to provide strong moment. However, the of CMG system easily falls into singularity, which renders actuator unable output required To solve singularity problem CMGs, law design based on cooperative game proposed. First, model constructed according quadratic programming problem, and strategy constructed. When weighting coefficient introduced carry out achieve optimal strategy. In theory, it proven that manipulation converges, sum frame angular velocities minimized, energy consumption small, there no torque error. Then, group simulated. near singular point, can quickly escape singularity. also Considering optimization momentum consumption, feasibility steering proven.

Cooperative aggregate production planning: a game theory approach
Production costs in general, and workforce and inventory costs in particular, constitute a large fraction of the operating costs of many manufacturing plants. We introduce cooperative aggregate production planning as a way to decrease these costs. That is, when production planning of two or more facilities (plants) is integrated, they can interchange workforce and products inventory; thus, thei...

متن کاملA mathematical model of the effect of subsidy transfer in cooperative advertising using differential game theory
This work deals with subsidy transfer from a manufacturer to a retailer through the distributor in cooperative advertising. While the retailer engages in local advertising, the manufacturer indirectly participates in retail advertising using advertising subsidy which is given to the distributor, who in turn transfers it to the retailer. The manufacturer is the Stackelberg game leader; the distr...
