The invention provides a hybrid excitation linear eddy current braking system. The hybrid excitation linear eddy current braking system comprises an electromagnetic braking assembly, a permanent magnet braking assembly and a coil winding assembly. The electromagnetic braking assembly and the permanent magnet braking assembly are both installed at the bottom of a train so as to induce eddy current with a rail and brake the train. The coil winding assembly is arranged in the length direction of the track and forms a secondary part of the linear motor, and the permanent magnet brake assembly forms a primary part of the linear motor. And the train is braked. Eddy braking force is generated through common excitation of the electromagnetic braking assembly and the permanent magnet braking assembly, and the total power consumption and weight of the train brake can be greatly reduced. Meanwhile, the coil winding assembly with the three-phase sine alternating current and the permanent magnet braking assembly below the bottom of the train form a secondary part and a primary part of the linear motor, electromagnetic force is generated by giving appropriate current, the horizontal component of the electromagnetic force also plays a braking role, and therefore the braking performance of the train can be improved.
