In this chapter, an LPV design example  that demonstrates how to design a dynamic, output-feedback gain scheduling controller using the LPV methods from Chap. 2 is presented. First, an LPV model is formulated from a family of linear models that were obtained from a series of closed-loop system identification tests for a variable valve timing cam phaser system . Then a control strategy is developed and relevant control structures are appended onto the LPV system to produce the generalized LPV plant. A discussion on weighting function selection for mixed controller synthesis is presented, with an emphasis placed on examining various frequency responses of the system.
