A nonlinear model predictive control scheme with variable terminal cost term

For the model predictive control problems of discrete-time nonlinear systems, we proposed an MPC scheme with a variable self-tuning terminal cost term, which made the terminal cost term has a variable self-tuning performance by inducing a self-tuning factor and setting different self-tuning laws to the self-tuning factor. In this paper, the average performance of the closed-loop system with a variable self-tuning terminal cost term has been proved. We proposed several self-tuning laws for the self-tuning factor, and analysed their performance respectively. The validity of the algorithm was proved by several examples.
