Abstract :
Energy conservation is a current requirement in the industry. This paper discusses an energy-optimal planning of a servo system, which is driven by a DC motor and a reduction gear. Controllable energy loss, such as Joule loss, Coulomb friction loss and viscous friction loss can be expressed by crossing time tc, when the input torque of the reduction gear is changed from positive to negative. In a position control system, minimization of the dissipated energy is determined by optimal crossing time tc. This conclusion is confirmed by simulations
