In order to obtain a non-overshoot and fast response in a servo system, approaches using nonlinear compensation actively have been proposed. This paper makes it clear that excelent performence can be obtained by using a hysteresis element in speed control system. This control law can be realized simply by changing the P element of PI controller into a non-linear hysteresis element. The finite time settling response which is non-overshoot and fast can be obtained. Therefore this control law is named Hysteresis plus Integral Control.In addition, it makes clear that control law is an expansion of Hysteresis feedback control which has been presented.The approach is examined by some simulations and experiments. As a result, it is confirmed that Hysteresis plus Integral Control is a effective law for finite time settling compensation of a servo system.
