Abstract This paper investigates the event‐triggered control of linear systems with saturated state feedback and observer‐based feedback, respectively. The problem simultaneously deriving stabilizing controllers tackling saturation nonlinearity is cast into a standard matrix inequalities problem. Key topics are studied, such as observer design synthesis. Important issues touched on, including existence positive lower bound for inter‐event times, self‐triggered algorithms.
The state of charge (SOC) estimation the battery is one important functions management system electric vehicle, and accurate SOC great significance to safe operation vehicle service life battery. Among existing methods, unscented Kalman filter (UKF) algorithm widely used for due its lossless transformation high accuracy. However, traditional UKF greatly affected by noise observation during estimation. Therefore, we took lithium cobalt oxide as analysis object, designed an adaptive (AUKF)...
