Control systems and methods for an electric power steering (EPS) system of a vehicle include obtaining, by a controller of the vehicle and from a set of sensors, a set of parameters of an electric motor of the EPS system, the EPS system further comprising a steering column and a steering wheel, and controlling, by the controller, the EPS system by based on the set of measured parameters of the electric motor, performing vector type recursive least squares estimation (RLSE) of a plurality of lumped EPS parameters including applying a variable forgetting factor, generating steering angle torque commands based on the estimated plurality of lumped EPS parameters, and controlling the electric motor of the EPS based on the generated steering angle torque commands for more accurate control of a trajectory of the vehicle.
