A soft variable structure control (SVSC) strategy based on S-class functions is addressed in this paper. Firstly, the definition of SVSC strategy is given, the structure of SVSC system under constrained control input is analyzed, and S-class functions with smoothness, strict monotonicity, and saturation are presented. Secondly, the sufficient condition on(More)
BACKGROUND How to improve the postoperative 5-year survival rate for lung cancer and to give more patients a chance of surgery have become research hot spots. The aim of this research is to evaluate the clinical and pathohistological responses and effects of preoperative bronchial artery infusion (BAI) chemotherapy in patients with locally advanced (stage(More)
This paper concerns the input-to-state stability (ISS) problems for a class of discrete-time nonlinear input-saturated switched descriptor systems (SDSs). An ISS criterion that only partial subsystems are exponentially stable is provided based on average dwell time method and discrete-time iterative algorithm. The proof difficulty is greatly decreased, and(More)
