True RMS-based inverse MR damper model for a semi-active system

In semi-active systems with MR dampers very often use of an inverse MR damper model is inevitable. The inverse model could be one of the crucial factors influencing system´s performance. Very often higher layer control algorithms´ output is the required force to be generated by the MR damper. Usually an inverse MR damper model is used to calculate the value of the necessary control signal to achieve the desired force. The paper presents an approach to inverse modeling of MR damper, which utilizes True RMS calculation of the desired force. That allows to use a very simple inverse MR damper model in semi-active system control, which output is the control signal to the MR damper.
