The paper investigates cooperative control strategies for spacecraft formations, also in case platforms are not homogeneous but differs in attitude control actuators. Specifically, either a common inertial or a time-varying pointing are considered as requirements for a formation of spacecraft, controlled either entirely by reaction wheels or partly by wheels and partly by thrusters. Two control strategies, namely the classical leader-follower or a more cooperative one, also labelled as behavioural based, where the kinematic state of each spacecraft is known to the others and enters in their command loop, are applied. In order to actually compute the actions, two controllers are considered: a classical proportionalderivative (PD) and an optimal one using the variable gain state dependent Riccati equation (SDRE). Numerical simulations to validate the approach are presented and, within this implementation, SDRE approach shows to succeed even in cases when PD fails
