| Abstract: | The design of model predictive control is studied for constrained continuous-time nonlinear systems.A univariate tunable predictive controller is constructed offline by using control Lyapunov function.The adjustable parameter which is similar to the decay rate of the closed-loop system is computed online by optimalized performance indexes.Meanwhile,the feasibility of this algorithm and stability of the closed-loop system are guaranteed by control Lyapunov function.Finally,a numerical simulation illustrates ... |
