Several kinds of cam motion curves are been utilized for the high speed positioning or the contour tracing. In order to realize the same performance by servo motors, the bang-bang control or the optimum control methods are used for the positioning. This paper describes a method to obtain the same as the cam motion by applying the inverse to DC motor driving system. We clarified the conditions to be able to obtain the motor motion equivalent to the practical dwell-rise-dwell cam motion curve with continuous velocity and acceleration characteristics at start and final points. And it was assured that the velocity feedback for the motor driving system reduces the effect of deviation of the real motor parameters for the setting values of the inverse. For the motor with an inertia load, the eqivalent motor output can be obtained by use of the inverse of the system with the time constant including the load.
