چکیده :

In this paper, the problem of output feedback tube-based model predictive control is discussed for a linear parameter varying system with inexact measurement of scheduling variables and subject to disturbances and noises. The measured values of the scheduling variables are different from the actual ones but the bounds on these errors are considered known. Also, the values of the scheduling variables in the future sampling instants are unknown. For these reasons an output feedback tube-based MPC is designed to deal with the uncertainty in the scheduling variables and also disturbances and noises. Scheduling tubes will be utilized based on inexact measurement and bounds on the rate of parameter variations and based on this, an MPC control strategy will be proposed. A numerical example demonstrates the performance of our proposed method.
