Finite-Time Super-Twisting Controller Based on SESO Design for RLV Re-Entry Phase

IEEE Access, 2019
In this paper, an improved extended state observer (ESO) based on sigmoid function and a finite-time convergence attitude controller are designed for reusable launch vehicle (RLV) in the re-entry phase. First, a control-oriented model (COM) of the RLV is

A Droop Control Strategy for Improving Reactive Power Sharing and Suppressing Frequency and Voltage Deviation in Islanded Microgrids

IEEE Access
Conventional droop control strategies use a fixed droop coefficients, which creates a contradiction between dynamic response speed and power output range. To address this problem, a variable droop coefficient control strategy based on sigmoid function is
