There are usually large uncertainties in the aerodynamic parameters of Mars entry vehicles, which inevitably degrades the performance of entry guidance algorithms. The paper presents a backstepping sliding mode controller for drag tracking in Mars entry guidance, which can guarantee the tracking error with finite-time convergence. First, the drag can track the reference trajectory under the virtual...
In this paper, a novel decentralized adaptive excitation control scheme is proposed for improvement of transient stability of large-scale power systems. The key feature of this control scheme is that by introducing two smooth functions and a bound estimation approach, the obstacle caused by time-varying interactions and unknown plant parameters is circumvented. We show that without the utilization...
In this technical note, we improve the results in a paper by Shi et al., in which problems of stochastic stability and sliding mode control for a class of linear continuous-time systems with stochastic jumps were considered. However, the system considered is switching stochastically between different subsystems, the dynamics of the jump system can not stay on each sliding surface of subsystems forever,...
