Summary: We consider dynamic feedback design for controlling the one-dimensional motion of a manipulator with a force/torque sensor. The control loop includes a digital computer, and the controller design accordingly relies on a discrete model of system dynamics. The model is linear and allows for elasticity of the manipulator structure (the chassis) as well as for the motion of the grip point over the object. The controller is designed in a linear-quadratic Gaussian framework. Despite the deviation of the linear model from the nonlinear properties of the real system, the design has improved the transient performance in manipulator experiments.
