Abstract: The motor and its drive control play a vital role in the massage chair system. Aiming at the problem of reduced comfort caused by weakness and unsteady in the process of starting or shifting control of the DC brush motor in the traditional massage chair,based on the open-loop control, the DC brush motor with Hall sensor was selected and the corresponding drive hardware circuit and incremental PID speed control software program were designed. After testing, compared with the traditional open-loop motor control method, this design has realized the improvement of the comfort of the massage chair.

Key words: massage chair, DC brush motor, incremental PID, speed loop
