Abstract :
In this paper, we analyze system uncertainty of time varying systems caused by identification of the least squares method. The errors between identification models and true systems at each time are investigated and we show that the radius of each corresponding uncertainty can be calculated in a statistical sense. The results are also applied to a design of closed loop systems by the gain scheduling for LPV systems
