Abstract
Examples of techniques for estimating stability margins in a steer-by-wire system are disclosed. In one example implementation, a method for open-loop steer-by-wire (SbW) system linearization includes linearizing, by a processing device, an open-loop SbW system at different operating points. The method further includes determining, by the processing device, an open-loop transfer function of the op en-loop SbW system. The method further includes estimating, by the processing device, margins of stability for the open-loop SbW system. The method further includes implementing the margins of stability into a vehicle to reduce instability in a steering system of the vehicle.
