Passive Dynamic Control (PDC) is a new type of mechanical system control method based on inherently safe design. It uses passive elements (braking effort) with variable characteristics positively. In this paper, PDC is applied to a material handling device, and a PDC air balancer is developed using a Magneto-Rheological (MR) brake and a torque sensor. Its control performance depends on the operation of the MR brake, not on the operation of air pressure. Compared with similar conventional devices, PDC air balancer is used with heavy objects for intuitive operation with lower highly-safe actuating force.
