Technical solutions are described for attenuating dither noise in a steering system. An example method includes computing a torque command based on an input torque, and generating a current command corresponding to the torque command. Further, the method includes determining an adjustment parameter based on a plurality of steering system signals. Further, the method includes reducing dither noise of the steering system by dynamically modifying a controller parameter value using the adjustment parameter. Further, the method includes generating a voltage command using the current command and the modified controller parameter value, the voltage command used to generate torque by a motor.
