A control system for placing controlled members in required positions including two control columns assigned to the controlled members to be moved, each control column having two degrees of freedom. Two actuators controlled by two control circuits apply to their associated control column either a resisting torque or a displacement torque. Each control column is provided with a mechanical spring system spring-loading the associated control column into its neutral position and adapted to provide, in the event of manipulation of the corresponding control column, a resisting torque in support of the resisting torque supplied by the associated actuator.
