This work presents a physics-based controlling system for bipeds Characters in a simulated environment, using reference motions. It consists of two components: Proportional- Derivative Control to mimic angular joints characteristics and balance control through the Transpose Jacobian composing for angular and linear momentum in the center of mass from caracter, using all parts of its body. The system is simple to implement and all the constants are determined by the user. The contact model aplied to the simplified foot model, confers to controller the ability to make the character follow locomotion movements or modify their stop posture, in both cases, adapting to external perturbations. The robustness of the controller is shown through a variety of movements such as walking front and back, squatting and raising, bowing, kicking and dancing capoeira. All these movements have a natural dynamics.
