This paper deals with new finite-time estimation algorithms for Linear Parameter Varying (LPV) discrete-time systems and their application to output feedback stabilization. Two exact schemes are proposed. The first scheme provides a direct explicit algorithm based on the use of delayed outputs, while second uses two combined asymptotic observers, connected by condition invertibility certain tim...

This paper extends the well-known concept, input-to-state stability (ISS), to finitetime control problems. In other words, a new concept, finite-time input-to-state stability (FTISS), along with related concepts such as finite-time input-output stability and finite-time small-gain theorems, is discussed, and then is applied to both the finite-time stability analysis and the finite-time stabiliz...

In this paper, the control Lyapunov function (CLF) approach is adopted to investigate finite-time attitude of rigid spacecraft subject parameter uncertainty and external disturbance. By using an extended state observer estimate disturbance, a CLF controller proposed for stabilization system. The designed includes two parts. first part classical based controller, which ensure globally asymptotic...
