A linear drive and a method for correcting a systematic error of the linear drive. The linear drive comprises a fixed assembly (1), a movable assembly (2), a first force sensor (3) and a second force sensor (4). The movable assembly (2) is movably connected to one end of the fixed assembly (1), and is capable of moving in a direction closer to or farther away from the fixed assembly (1). The first force sensor (3) is arranged at one end of the fixed assembly (1) away from the movable assembly (2) to detect a force acting on the first force sensor (3) in a direction from the fixed assembly (1) towards the movable assembly(2). The second force sensor (4) is arranged at one end of the movable assembly (2) away from the fixed assembly (1) to detect a force acting on the second force sensor (4) in a direction from the movable assembly (2) towards the fixed assembly (1). The linear drive detects, by means of the first force sensor (3), a reaction force on the fixed assembly (1) by a fixed object, such that the magn
