The invention discloses a control system with masterslave controllers. The control system comprises the first controller and the second controller. The first controller and the second controller are electrically connected through a bus. The first controller sends a command signal to the second controller, and therefore a near end oil cylinder and a far end oil cylinder are controlled by the first controller. The second controller sends a command signal to the first controller, and therefore the near end oil cylinder and the far end oil cylinder are controlled through the second controller. The control system comprises at least two controllers, the multiple controllers are masterslave and distributed at different positions of a belt self-moving tail, the master and slave modes of the multiple controllers can be automatically switched according to selection of operation staff, and in-place real-time control over the belt self-moving tail is achieved; and meanwhile, the control system can be extended to enable the multiple controllers to be masterslave, remote multi-point real-time control is achieved, and the system signal input an output magnitude can be correspondingly extended.
