In this paper. stability is studied for a class of switched singular systems containing both stable and unstable modes. By introducing a time-varying piecewise Lyapunov function (TVPLF) and a mode-dependent average dwell time (ADT) switching rule. the computable sufficient conditions for system stability are derived. https://allfixelectricales.shop/product-category/dishwasher-comfortlift-guide-bearing/
