| 英文摘要 |
| Model predictive control (MPC) has been widely applied in modern control due to its advantages in handling
multivariable and constrained systems. However, the uncertainties and input delays of the systems pose significant challenges to the design and implementation of MPC. This paper proposes an adaptive Tube-MPC algorithm for linear systems
with parameter uncertainties and input delays. Firstly, the original system is transformed into an augmented system using
the state variable extension to address the delay problem. An adaptive updating law with time-varying update rates is designed for parameter estimation, ensuring that the estimation error remains bounded. Secondly, the MPC controller uses
ellipsoidal sets to parameterize the state Tube to capture the state trajectories. The offline and online optimization problems
are converted into semi-definite programming (SDP) problems, simplifying computational complexity and achieving robust
control of the system. Finally, two sets of simulation examples are used to verify the effectiveness of the proposed adaptive
Tube-MPC algorithm. |
