Robustness Analysis of a 2-Degrees of Freedom Linear Quadratic Gaussian Position Control (2DOF LQG Control) of the Front Axle Actuator for a Steer-by-Wire Steering System
control of the SbW Front Axle Actuator represents an essential prerequisite. For fulfilling the high requirements to reference tracking, disturbance rejection, stability, and robustness a Two-Degrees-of-Freedom [...] dynamic uncertainty models were defined and introduced into the control loop. Moreover, performance requirements to the command and disturbance response were modeled by respective weighting functions in frequency [...] find the smallest normalized perturbation, which leads to a violation of stability or performance requirements. The reciprocal value of this smallest normalized perturbation is called the structured singular …
