In this contribution, a four-bar linkage having a variable input velocity is studied, traditionally it is assumed to be constant.\nThe advantages of a variable input velocity mechanism, in contrast to a mechanism driven by constant velocity, are the\nflexibility of the output motion (and/or improved kinematic and dynamic characteristics). The velocity of the crank is\ncontrolled in order to obtain the desired output motion at the coupler point. The input velocity trajectory and the controller\nparameters are considered as design variables, such that the kinematic and dynamic requirements are fulfilled.\nTwo numerical examples are provided to corroborate the result.
