— This paper applies fractional order P ID k controller to torsional system's backlash vibration suppression control, in which the order k of D controller can not only be integer but also be any real number. In order to improve control system's robustness against backlash non-linearity, several methods have been proposed. However their design processes are(More)
Estimation of state of charge (SOC) is of great importance for lithium-ion (Li-ion) batteries used in electric vehicles. This paper presents a state of charge estimation method using nonlinear predictive filter (NPF) and evaluates the proposed method on the lithium-ion batteries with different chemistries. Contrary to most conventional filters which usually(More)
