In this paper the different phases of Gain Scheduling are visited, with special attention to stability results for LPV systems. Given that the main reviews in the area date from 2000, more recent results were gathered. Stability is to be shown mainly with Parameter Dependent Lyapunov Functions, and a discussion on performance analysis is presented. At the end, a procedure for the Synthesis and Analysis of a Gain Scheduled LPV controller is presented based on the different results presented. This procedure is simpler than the purely theoretical ones, and still more reliable than pure simulation, as it is often the case in industrial applications.
