Second-Order Discrete-Time Sliding Mode Observer for State of Charge Determination Based on a Dynamic Resistance Li-Ion Battery Model
A second-order discrete-time sliding mode observer (DSMO)-based method is proposed to estimate the state of charge (SOC) of a Li-ion battery. Unlike the first-order sliding mode approach, the proposed method eliminates the chattering phenomenon in SOC estimation. Further, a battery model with a dynamic resistance is also proposed to improve the accuracy of the battery model. Similar to actual b...
متن کاملSecond Order Sliding Mode Observer-Based Control for Uncertain Nonlinear MEMS Optical Switch
This paper studies theuncertain nonlinear dynamics of a MEMS optical switch addressing electrical, mechanical and optical subsystems. Recently, MEMS optical switch has had significant merits in reliability, control voltage requirements and power consumption. However, an inherent weakness in designing control for such systems is unavailability of switch position information at all times due to t...
متن کاملHyperplane Design in Observer-based Discrete-time Sliding Mode Control Hyperplane Design in Observer-based Discrete-time Sliding Mode Control
A new result that allows the selection of sliding hyperplane coeecients in Observer-Based Discrete-Time Sliding Mode Control (OBDSMC) is presented. Selection of co-eecients is done by analyzing the tracking error dynamics inside the boundary layer-where the closed-loop system has a linear state feedback connguration-rather than assuming that the sliding function has already converged to zero. T...

متن کاملA Novel Approach to Designing of Chattering-Free Sliding-Mode Control in Second-Order Discrete-Time Systems
In this paper, a chattering-free sliding-mode control is mainly proposed in a second-order discrete-time system. For achieving this purpose, firstly, a suitable control law would be derived by using the discrete-time Lyapunov stability theory and the sliding-mode concept. Then the input constraint is taken into account as a saturation function in the proposed control law. In order to guarantee ...
