Abstract

The present process of controlling an industrial robot includes steps consisting of calculating a time-dependent composite setpoint defining articular forces and/or velocities, according to a target trajectory and to an operating mode; calculating (S106) a behavior matrix which describes a desired behavior of the robot arm, defining directions along which the calculated composite setpoint is to be applied; calculating (S108) an articular force setpoint for controlling the axis controller module and calculating the time derivative of a homogeneous internal state at an articular position. The articular force setpoint for controlling the axis controller module is calculated from a control function which adjusts the difference between the articular position and the internal state determined by integrating said time derivative of the internal state.
