This paper presents current control for stepper motor with an adaptive gain super twisting algorithm. The conventional super twisting algorithm has limitations on that the bound of distuYourbances is known. However, in practice, the bound of disturbances change. Therefore, we adopt the adaptive gain super twisting algorithm to perform the position control of permanent magnet stepper motor, which guarantees the finite-time convergence with unknown boundary. With the numerical simulation, we validate the effectiveness of the proposed method.
