In this paper, an adaptive dynamic surface control is proposed for a class of completely non‐affine nonlinear systems preceded by the generalized Prandtl–Ishlinskii (P‐I) hysteresis, in which the hysteresis input function is also non‐affine with respect to the control input. Instead of the mean value theorem widely used in existing literature, new nonlinear functions are introduced, leading to the...
A dual unscented Kalman filter (DUKF) is used to estimate the state and the parameter simultaneously via two parallel unscented Kalman filters. The original DUKF usually has performance degradation as a result of assuming the control inputs of each filter are constant, which usually are disturbance inputs or systematic measurement errors in the control system. An improved dual unscented Kalman filter...
