Madara has no intention of using the Jūbi for the 'Eye of the Moon Plan' that was just a ploy used to trick Obito, he's just using it for power and to gain control over the world.
Actually, Madara dos want to cast infinite tsykuyomi but he can't because 1; Naruto and the others would get annoying and 2; it takes time to summon the moon and cast eye of moon plan jutsu. For now, Madara is trying out the juubi's power.
